Hey, I have an O-Chem exam coming up covering Sn1,Sn2, E1, E2, Hydrogenation, Hydroboration, The Bromonium ion reaction (forgot the technical name) the Oxyonium ion reaction and a few others I am sure I am forgetting. My question is: I have done problems, and looked at all the mechanisims involved, but I still don't feel completely ready. Does anyone have any suggestions for doing well on this material? Any "tricks" that worked for you? Thanks!
