This blog may help JC ( Junior College) students in Singapore to cope with the Cambridge-Singapore GCE A level (H2) assessment. Organic Chemistry occupies a distinctive and important position in the Singapore Chemistry syllabus.
In the new academic year, we need to plan our time wisely. Setting goals for what we want to achieve this year and motivating ourselves to accomplish the tasks ahead despite obstacles, are imperative. The challenge is to better ourselves and specifically, for chemistry, is to be curious about the world of atoms, molecules and ions.
Do keep an open mind and be positive about learning the analytical skills in chemistry that will be for use in applications throughout your adult life.
If you have tuition with me, I will try to help you to secure the basics. The below topics are actually quite optional and I shall do with you only when you are ready or we may not do them at all. So do not worry!!!! :)
You may like to read up on:
- selective precipitation (in a university general chemistry textbook such as Chemical Principles by Zumdahl. I like this textbook a lot.)
You may also like to explore isomerism in transition metal chemistry in the Zumdahl textbook, which is in university chemistry syllabus but may appear in prelim papers.
Let us be consistent in our daily reading of lectures, and do our tutorials faithfully (I know that the sense of weariness of doing tutorials has set in; it is the time for half done tutorials in JC2; been there, done that before. But keep pressing on!!! You can do it and achieve it for your dream course in university or some other routes!!! Sometimes setbacks can be a catalyst for even greater success, as a start-up entrepreneur shared in her latest book!!)
There have been many additions to the contents of International Cambridge Chemistry exam syllabus in 2016. Those who are "super on" can learn a little of the new additions to prepare for your prelim exams.
2016 syllabus : http://papers.xtremepapers.com/CIE/Cambridge%20International%20A%20and%20AS%20Level/Chemistry%20%289701%29/9701_y16_sy.pdf
Many JC teachers have taken materials from university organic chemistry textbooks and setting new reactions in the prelim papers beyond the scope of H2 and H3 syllabuses. So just be prepared!!
Please pay close attention to organic chemistry topics, as this section is highly important. When you are ready for the challenge, you may want to reproduce summarised reaction charts (with reagents and reaction conditions) by functional groups of all reactions in organic chemistry. Hence, it makes sense to go to the library and get a book on speed memory techniques since lots of memory work (and more importantly, understanding) is needed for chemistry.
Arrow pushing mechanism in organic chemistry
You may like to ask your tutor to teach you arrow pushing mechanisms in organic chemistry. This is only fully taught in year 2 NUS/NTU, and has been brought down to A levels in last year's exams.
There is an organic chemistry textbook that is published in 2012 that is written by 3 authors, one of whom is a Cambridge University author. Since Cambridge University examiners set the exams, you may get some clues from this textbook.
Here it is:
Title : Organic Chemistry (2nd edition)
Authors : Jonathan Clayden, Nick Greeves, Stuart Warren
Publisher : Oxford University Press
You may like to briefly scan through it and get prepared to tackle higher order thinking questions in the exams. If you keep cool in exams and extend your knowledge of chemistry concepts, you should be able to tackle novel problems in the exams. This textbook is not written in a simple fashion and is more targeted at university senior undergraduates.
You may like to study on chirality - meso and diastereomers molecules. This is in the H3 syllabus but it came out in 2012 H2 papers.
Mr Maverick Puah, a famous chem tutor in Singapore, has posted sometime ago on his facebook updates on crown ethers. I also favoured this last year, and there is a question which has an organic molecule that resembles crown ether in 2013 exam papers. So you may like to wiki on it.
But you have to secure your basics first. These things that I mention are the optionals that give you an edge in chemistry.
The examiners are gonna set some NUS/NTU year 1/2 questions in this year's Cambridge papers. So there will be new reactions and functional groups not encountered in A levels that you have never seen before in organic chemistry, but they will be an extension to what you have learned before. So keep cool and get your fundamentals right.
<<For more secrets to scoring in A level Chemistry, try tuition with Mr Chong, the blog owner! Contact Mr Chong, the tutor, at 85862339.>>
If Cambridge employs new examiners this year, the style will change drastically again. Be prepared for uncertainties in the chemistry exams!!
Organic Chemistry questions are highly likely to take up more than 50% of your prelim exam papers. So prepare adequately for them. Physical chem questions maybe occupy about 30%. This is just a rough guide as it varies from JC to JC (Junior College).
You may want to ask your teacher nicely to give your class many organic chemistry elucidation questions in Mar - Apr 2015. The examiners favor structural elucidation problems in organic chemistry. You can find some problems in past S papers (the H3 equivalent before the year 2005) or in prelim packages. So, you may like to request from your teachers for some S papers.
Also, if your class is game for challenge, ask your teacher, if appropriate, to teach your class some H3 / old syllabus S paper / university 1st year organic chemistry. Cambridge is literally operating without a syllabus nowadays. Anything up to PhD level materials can appear. So be prepared. I am just concerned that Cambridge may suddenly increase the level of difficulty in physical chem questions this year. By what means? They just select some questions from 1st year university textbooks and modify them. It is really an uphill task for students. So master your basic materials and be prepared to do more to get a distinction.
I noticed that since 2010 exams, examiners have been using university organic chemical reactions in papers. There are also functional groups taught in university level , just for an example: thiols, -SH. Examiners can set the exam paper in a contextual situation. If the examiner continues the same trend, organic chemistry is going to be atypical this year. So an examiner may take a recent university organic chemistry textbook or his own research interests, then finds some functional groups not in A level syllabus. Next, he finds some reactions in the textbook, and sets the problem.
By the way, medicinal (drug) chemistry and biochemistry may be the hottest trends among researchers right now.
My ex-student who has gotten a Masters in Chemistry did not know of 2013 chem papers, but yet told me about the optical activity of tartaric acid when I asked him to suggest two A level questions. Tartaric acid came out in 2013 Cambridge papers and he was spot-on.
Another question he suggested was on enzymes. So you may want to study Chemical kinetics - enzymes and also proteins in organic chemistry. Sometimes, intuition can prove to be better than logic. A question really came out in 2014 exam papers.
Those who have a little time to spare and are game for the challenges, you may desire to practise John McMurry's Organic Chemistry textbook questions, especially those of the latter chapters, eg. hydroxy compounds, ***** carbonyl compounds. (real important topic!!) *****
You are still up to the challenge!!! Our brain structures are complex enough to adapt and generate new neural connections.You may want to ask your teacher to teach you about resonance. It is out of syllabus but this term appeared in MCQ 2012 Cambridge exam papers.
Also, if your teacher did not teach Williamson ether synthesis in halogeno derivatives, please learn it.
Group VII chemistry
Pls take note that Cambridge really likes Group VII elements topic. Though inorganic chemistry seems to be memory work all the way through, there are some trends and tricks to take note of.
** A level chemistry tuition is available. Pls contact (sms) Mr Chong at 85862339 or e-mail me at email@example.com. More 'secrets' to reveal in my coaching sessions.
Some topics to take note of
You may like to revise chemical bonding (a tricky topic), energetics (an important topic) and organic chemistry if you school has started on organic chem. As there is great continuity in the topics for organic chemistry, the minimum you can do in your free time is to revise your organic chemistry, as 2015 will be booming at higher speeds.
For those schools that did ionic equilibria, it is a very difficult topic. So revise it and practise a few questions here and there.
You can also do mind maps for some of the topics you are unsure of. Using analogies, similarities and contrasts can be another method to ensure your learning.
Ask your school mates for ideas. Collaboration is the key in the 21st century world.
International Cambridge exam papers
International Cambridge 2013 exam papers are out in xtremepapers.com You may like to scan through the papers and analyse the trends that the examiners are laying out. The Cambridge Pre-U papers are also out, and are tougher than the traditional Cambridge International papers. Your papers will be more difficult than International Cambridge papers 2012.
If you have the time, you may want to practise the latest International Cambridge chemistry papers at xtremepapers.com , just in case Cambridge sets similar questions from that paper. BedokFunland JC tutor has claimed that Cambridge modified some of the International chem papers of 2010 and 2011 in Paper 2 and 3. If you like to attempt International Cambridge papers, which is of a slightly different syllabus, and generally much easier than Singapore papers: the website is here: xtremepapers.com
I am not sure of the safety of the website, which may have malwares.
Practical Applications of Chemistry
-- Older post written in 2011-2012; revised in Dec 2013
Information for those aiming for a distinction in H2 chemistry in the year 2015:
This section is a joint project between BedokFunland JC (http://infinity.usanethosting.com/Tuition/) and myself.
Thank you BedokFunland JC for your invaluable advice!
An experiment on extraction of organic molecule citral from lemongrass. Partition coefficient and solvent extraction are involved. You may want to scan through the theory and look at the procedure:
Another experiment on extracting an organic compound from nutmeg:
For the extraction of caffeine (a possible Paper 2 planning question), pls look at : https://teach.lanecc.edu/thompsonj/CH241/laboratory/Caffeine%20Extraction.pdf
Do you know how to draw the Lewis structure of HgC2N2O2? Wiki for mercury fulminate to check the answers.
Maybe you like to do the Cambridge exam papers from 2007-2014. If you can grab hold of the prelim papers 2014, you may like to try a few of them too. Can you pick up any trends?
Maybe the strategy now could be to brush up on the theory aspect of weaker topics and to practise lots of Singapore-Cambridge exam papers, and a little prelim papers (if you can grab some 2014 prelim papers, if not 2013 papers).
Group VII elements
You may like to study the effects of dilute aqueous ammonia and concentrated ammonia on chloride, bromide and iodide ions. This is found in the chapter of Group VII and also ionic equilibria.
Will Cambridge like H-O-N=O? Or HClO3? Or CNBr? Or H2C=N-H? Or Br-CN? Or NOCl? Or C2O4 (2-), HC2O4(-), H2C2O4? Or AgIO3? Or HClO4? Or Ag3AsO4? Or NH2OH?
Not sure whether global warming may come out in exams? Do you know the greenhouse gas (GHG) nitrous oxide (laughing gas) N2O has chemical structure N=N=O? Try working out the dot and cross diagram. Also, can you name three greenhouse gases?
Are there anything special about the bond lengths of the C-C and C=C bonds in buta-1,3-diene? Wiki- about this molecule. (Topic: conjugation in diene compounds)
Heating magnesium carbide in nitrogen produces magnesium cyanamide:
MgC2 + N2 --> MgNCN + C
Draw the dot and cross diagram of C2(2-) ion and cyanamide (NCN(2-) ion. "
Do you happen to know the dot and cross diagrams of cyanate, isocyanate, thiocyanate, chlorate(V), chlorate(VII), chlorate(III) ions, iodic acid and hypobromous acid? Wiki for these species.
How about types of hybridization of non-hydrogen atoms in CH3CN and HN=NH molecules?
Compare pKa of EtNH4+ and Et3NH+ ions where Et stands for an ethyl group.
Carbon suboxide, or tricarbon dioxide, is an oxide of carbon with chemical formula C3O2 or O=C=C=C=O. (Courtesy of www.wikipedia.org) Will Cambridge like such molecules? It has come out before in the papers. It is your guess and my guess.
You may want to look at spider silk (a protein that has beta-pleated sheets).
You may want to google for Ni(CO)4 (nickel carbonyl complexes).
A trick about organic chemistry
For organic chemistry mechanisms, you need to learn them well and reproduce them almost perfectly in the exams. Organic chemistry is understanding first, then memory work is next. In a chemical reaction, first understand which functional groups are changed as you go from reactants to products, and identify the electronegativity (please revise this in both chemical bonding and organic chemistry), nucleophile, electrophile or free radical, and check whether it is a substitution, addition, elimination or others reaction. Lastly, it is to remember the reaction conditions and catalysts. There are usually reasons why certain catalysts are used in certain reactions.
How to tackle organic chemistry
For organic chemistry, first understand the mechanism behind the reaction, then check the before and after (reactants and products) to see the which atoms or functional groups have been changed. (A little like the slimming ads where you compare the person before and after slimming. What changed before and after????) Lastly, understand why the reaction conditions are used. Then, "memorise" the reaction conditions. Many of the reactions require heating or reflux.
For some chapters, you need to know the details of the mechanisms very well. It requires some knowledge of nucleophiles, electrophiles or free radicals and the electron flow (eg. electrophilic or nucleophilic attacks). Next is to know whether the reaction is an addition, substitution or elimination or even redox reaction. (or other types of reactions)
After understanding the reactions, next is to commit into memory the reaction conditions and to practise as many questions as possible.
You may like to look at bio-inorganic molecules, such as haemocyanin, myoglobin, haemerythrin, cytochromes P-450 briefly as I suspect that one of the examiners has training in bio-inorganic chemistry. Please use wikipedia or refer to an inorganic chemistry textbook in National Library or your school library.
**** Drawing inspiration from Rod Beavon's chemistry site, you may want to look at esters, fats and oils.
For 3 challenging exam style questions (mainly on organic chemistry, pls see : http://alevelchemistrysg.blogspot.com/2012/03/fun-questions-inspired-by-research.html )
For a fun proteins question, please refer to my blog's side-bar. Proteins are almost 100% guaranteed to appear in your school's assessment or in the national exams.
OPTIONAL TOPICS TO EXPLORE
Good Knowledge to learn if you are aiming for a distinction in chemistry:
Stay cool! (: It is a long list, but you may just want to study some topics. Chemistry fanatics may spend much more time on the advanced A level topics!

Some general advice
Work life may be more challenging than school life in the Shenton Way area; so cherish your study life. Global situations are really unpredictable in the 21st century. With you going to the workforce in the next 4-7 years, will Singapore still be competitive in 2020?
Listen to your passions and heart. What is your path after A levels? Success in life is about finding your sweet spot and developing in your passion area. A doctor or a teacher or an artist can be very happy serving in a rural area and earning little money.
Be adequately prepared. My advice is to have sufficient sleep the day before chemistry exams and be prepared for surprises during the exam. Keep cool, dudes!!!
Let me clarify my stand on JC lecture materials and the Copyright Act. The Copyright Act is grossly outdated and some authors have argued for an overhaul of the Copyright Act in US in the internet age. With Google and Coursera, my idea is that if every JC puts its lecture and tutorial materials on the website(s) for all to view, students' standards should theoretically be raised. I feel that knowledge should be shared and collaboration is the key to success in the 21st century of uncertainties and seismic changes.
You may desire to analyse the trends in the Cambridge papers of 2010-2014, as your teachers may set questions that are similar to the papers in the prelim exams.
Set goals for what we want to achieve this year. Set your sight on greater things! Most of your parents and teachers have prepared you well for education, and the rest is for us to overcome hurdles! Next is to be consistent in little things. Your daily habits will determine what your end journey at JC will be. Have an overcoming attitude! Let us be strong!
An important thing is to grasp the gist of every lecture and tutorial.
You may like to do some physical exercises to prepare yourselves for a challenging year ahead! Also, Being emotionally healthy, eg. not bearing grudges, does help you indirectly in studies as you can concentrate better in studies. Do not worry, be happy!!!! :-)
You can do it! You can surmount the barriers and fly as an eagle in 2013! Your dreams can come true!
Do plan your CCA activities well, as CCA records are needed for entry to universities and some faculties need good CCA records. Well, it is not just points and grades in CCA. More importantly, is to have passion in your CCA and not just go through the motions. We only have one life, so live it well and to the fullest. :)
What can you do for chemistry? Do you still like chemistry and your chemistry teachers? One important thing is to befriend chemistry and like chemistry and have some passion for this subject, even if you may not touch it the rest of your life after A levels.
A good way is to make your own notes, or at least underline your notes. Some of my students draw cute cartoons here and there in their lecture notes....
All the best! Network with your classmates. You are bound to need help from them at some point or another. Life is mostly about treasured relationships. Grades are not everything.
Time management is crucial in this hypercompetitive education system.
If your school has not finished the entire chemistry syllabus in mid-May, you may want to read ahead so that you could be adequately prepared for prelim 1 and prelim 2 exams. I know life is very stressful in JC, and this is the price we have to pay for having one of the best education system in the world. So play the game, pay the price and you will be amply rewarded. If you start studying only in Jun, it may be too late. This is a reminder, and a gentle one! (From one who has seen at least 1000 students go thru this system).
Anyway, how does one measure success? In terms of money, status and power? Is that the right way of measuring people? This question begs a debate. Our Singapore system may have too narrow a definition of success.
The bar for tests and exams has been raised. But say you can! You can! You can! Just do it!
We can learn from sports psychology. Michael Phelps, the great swimmer, psyches himself up before every race. So, similarly this A levels assessment is also a mind and psychological game. Even if the exam is tough, psych yourself that you will be tougher than the others. You have the resilience. Confess good words. Declare yourself a victor and celebrate (a little) victory even before the exams is coming. Being emotionally healthy is highly important. Inject yourself with doses of good and inspirational words : "I will conquer! I am a victor!"
For those who are a little knocked down before, get up. It is time to get up. Time is precious. Redeem the time. Get up! And keep fighting! Surround yourself with positive people! It is a mind game. Get up and start fighting. Like a boxing match, the one who lasts the longest and is not out of the ring wins. Get up!
There are motivational books and inspirational websites. Get your morning happy. Mornings are the most crucial moments of the day. Get yourself psych up. You know the methods yourself.
Some students sabotage themselves by telling themselves subconsciously they do not like a particular subject. It is no wonder they do not excel in the subject. Excellence begins in the mind-set and paradigm. You can do it.... Just do it.... And do the right thing....!!!
If you can finish all of 2014 prelim papers of many JCs, the chances of you getting an A or a B may be higher. It is all about making few mistakes in exams and getting the right answers for the examiners that matter. Interpretation of question is an important key to scoring in the exams. We need not be long-winded in our answers. (You may find me super-duper long winded, haha....)
You may want to purchase HCI Organic Chemistry Summary booklet (now on sale in Popular bookshop at $8) or do summary reactions for each functional group in organic chemistry.
All the best to your Paper 3! Pls read through all the 5 questions carefully and eliminate the question which you feel you may not score very well in. Time management is crucial. You need to be concise in your descriptive answers and yet the key words have to be in the answers. Do the calculation questions carefully as the different parts of the question are usually interlinked.
To prepare for Paper 3, you may want to read some of Ultimaonline (aka BedokFunland JC) website for some of the FAQs. These questions are reflective of the latest trends of Cambridge questions. His answers are generally pitched at JC2 and NUS/NTU undergrad year 1 standards.
His website can be found at the right side-bar of my webpage. All the best!
I have uploaded some questions for both JC1 and JC2 students.
******* Understanding chemistry is not to memorise the whole chunk of notes. Smart students ask themselves what the concepts are: eg. electron flow, arrow pushing, guessing which gases or other products are generated in a chemical reaction (smart guess), summarizing notes in their own words. Some students think of wacky short-cuts to help them remember concepts. (Thanks, Adam Khoo LTG!) Also, a visual learner may use a lot of highlighter and mind-maps, diagrams, tables and charts and summary of reactions and their reaction conditions to help them remember.
One of my students who was hungry for success remembers by keywords and association (neuroscience technique). Ask your smart classmates for some tips. Be nice!
A very useful advice from rsc.org (a chemical society) for tackling Paper 3 of Chemistry exams:
"Some of the questions will contain material you will not be familiar with.
However, by logically applying the skills you have learnt as a chemist, you should be able to work through the problems. There are different ways to approach the tasks – even if you cannot complete certain parts of a question, you may still find subsequent parts straightforward. "
*** For those JC2s who are really struggling in chemistry, please try to get your foundational topics right. Ask for help from your classmates. You may also want to seek help from tuition centres or private tutors or internet forums. Or e-mail openlectures.sg and ask if the scholars can help you. Please start to revise now! Time and tide wait for no man!
Confess good words and positive thoughts.
Religion is a powerful force. Those who are open can seek help from the Person Upstairs.
Thank you everyone for journeying with me in 2014. What a year! May it be an enriching year for you.
May 2015 be a great year for all of you!
It is my pleasure to serve you all in these blogs.
All the best for your future endeavours!

God bless you!!
P.S. The more you are exposed to chemistry concepts, the more you understand the paradigm of the scientists. Make chemistry a delight, not a duty or a chore. And you will score well. Be curious! Do not worry, even if you do not read any of these topics, you can still keep cool in exams and solve the problems. You just require more thinking on the spot!
You may use wikipedia to read more about the topics mentioned above.
# Mr Chong is not responsible for any inaccuracies or the topics he highlighted that do / do not appear in assessments. Chemistry knowledge is vast and examiners have a large scope to test for in exam papers.
