NUS Chemistry Module Review: CM2121 Organic Chemistry 2

Starts off with spectroscopy (IR, NMR, MS), before going into enolate chemistry. Basically all the reactions in this module involves or relates to enolate chemistry, which is fair because there is a lot of stuff. Everything up till the middle of enolate chemistry is taught by Dr Wu. Then after recess week, Dr Ge takes over to finish up enolate and go into chemoselectivity, retrosynthesis, and diastereoselectivity.

As with all organic modules, it’s not exactly something easy. Trying to solve the questions (in tutorials, tests, exams) involve a lot of application of the concepts learnt, and oftentimes you find that you feel like you kind of understand it, but when you see the question you’re stumped. But next when you see the answer, you realise it’s something you should have been able to solve. You do need a lot of practice for this, but you will have to find your own practice questions (e.g. check Clayden textbook, ask from seniors) because the lecturer did not believe in giving us the PYP since the question wouldn’t come out again. (I do not follow that logic but ok)

The chapters follow the textbook chapters intensely, much like CM1121. That being said, I believe that one of my bigger regrets when it comes to organic chemistry was relying too much on the lectures, and not reading the textbook more. I feel like the textbook contains more information and random tidbits, like the annotations that go like “Remember XXX you learnt in Chapter X? This thing relates to that!”, which do help with the understanding and connection of concepts.
