ochem section (DAT preparation master list)

Members do not see this ad.

so i was wondering for you guys who already took the DAT, if you could help chip in one or 2 things you think one MUST cover to do well on the ochem part. looking at the threads, i get a feeling that destroyer is too much info (but the road maps are a must), that we should know NMR...what else? naming? specific main rxns (aldol condenstaion, markovnikov)

so just ADD TO THE LIST or edit mine:

1. Destroyer Road Maps...what else from destroyer ochem is a must study?
2. NMR (know the absorbance values for functional grps, how to read peaks?)
3. naming structures

PS: should i focus on aromaticity? that thing is tripping me up, i dont get the p-orbital exception thing (sp2?), etc

THANKS

Ya, you should know aromaticity. Every carbon must be sp2, there has to be 4n+2 pi electrons, and it must be planar.
