The first really interesting reaction seen by Organic Chemistry students is the Diels-Alder [4+2] cycloaddition, an example of a concerted process where all the bond making and breaking take place concomitantly. The SN2 is also a concerted process, however the Diels-Alder reaction is a gem because of the high density of relative stereochemistry that can be established in a single synthetic step. The most interesting and unique of all organic reactions learned fall within the narrow category of sigmatropic rearrangements, intramolecular pericyclic processes wherein one σ-bond is exchanged for another σ-bond. Example reactions are the Cope and Claisen rearrangements.
Mostly every student I’ve ever tutored wanted an “A” in Organic Chemistry. What is the meaning of an “A”? It means you’ve mastered the subject. Like Qui-Gon Jinn, you’ve become a Jedi Master (of O-Chem). This takes dedication, perseverance and hard work.
Indicated are some tips I’ve picked up along the way to help you get that “A” you want so much!
