Title: I need some tips for studying
Post by: alexcve on December 09, 2024, 07:59:11 AM
Next year i'm applying to med school and the most common type of question  in the org  chem exam is to do a chain of conversions. For example  you start with Methane and you have to convert it to Ethane and then convert the Ethane to something else. (  For example to get to Ethane you  first react the methane with cl2 and then do a Wurtz synthesis and describe the process ).
I however struggle with some that are quite tricky. For example how to get from ethanal to methanal or ethanal to propane are quite hard to me and i don't even know where to begin. Just memorizing every reaction is not possible and i'm missing some concepts. Thanks in advance!

For this you have to study organic chemistry first. Probably need 2 year for this.
For your question check reaction like Hoffmann, Curtius, Lossen, reaction for shorten C chain..
Also Grignard to extend C chain.

i've been studying for awhile now and i  understand most of them, but i struggle with some of the most complex ones. Thanks for the recommendations!

Its a bit stupid with these examples, few use Wurtz coupling today and nobody makes these molecules this way, it could be better with up-to-date reactions and useful examples

No kidding! I've done every Organics class my university offers (both undergrad and grad), and I've never even heard of it.
