Hey SDNers - does anyone happen to have compiled a listed of the Organic Rxn's from Kaplan? I am having a hard time picking out which ones are the most pertinent to memorize - would be greatly appreciated

Hey, I would advise you to look through the Kaplan book and pick out all the ones you don't have memorized and/or can't work out the mechanism in your head...that way you're aware of what you know and don't know and then you can proceed to copy them all down on other sheets of paper...writing them out over and over as well as explaining them out loud to other people or to yourself helps your mind associate each reaction with it's proper reagent and mechanism...you should make your own list because it will be more personal and thus, easier to learn...hoped this helped

Hey, thanks, I am not the best on the organic section and am terrified of it, really! I was never that great with mechanisms so I want to try to get them all down. I guess just Sn1, Sn2, E1, E2 etc. How many specific rxn's do u think are necessary - like diels alder etc?

if you wanna do well on that section, I would try to memorize all of them. Not THAT many compared to how many I had to memorize for a ochem class final.

know all of them listed in kaplan plus the diels alder. remember to study steriochemistry and nomenclature also.

I know people say memorizing is the best thing to do, but I found that I just couldn't memorize and keep everything straight in my head. While I was taking Ochem, what I would do is write out the mechanisms, time consuming, yes, but after just copying them down a few times, I could remember them quite easily.

Possibly what you could do is to just look at the rxns in Kaplan, go to your textbook and look at the mechanisms. Then talk yourself through the entire thing. So for example for HBr adding to an alkene you would go, The H adds to the carbon with the most H's on it, then the double bond goes away and you have a carbocation. Here you will have a chance of rearrangement. DO I have the most stable carbocation? Yes, okay so then the Br would attach to the carbocation. Or No, so there would be a 1,2 hydride shift or there will be a 1,2 methyl shift.

This method might help you to remember the reaction order and those PESKY little rules about rearrangement and stereochemistry.
