how to get around organic chemistry? 10/20/15 (Tue) 14:19:21 No.3245

this might not be the best place ask this question or it might just be. can anyone suggest few tricks or anything such to make organic chemistry.. my professor says it all about logic, the reactions, but the mechanisms are very confusing.at times

Most of the time just pay attention to electron density. Which atom has decreased, which atom has increased electron density, either because of bond resonance or because of electronegativity differences. A large portion of organic reactions is when an atom with increased electron density (a nucleophile) bonds with an atom of decreased electron density (an electrophile) of another (or sometimes inside the same) molecule.

Also, whenever you have the reaction partially done (in intermediate stage), think if there's any possible bond rearrangement. Is there a π-bond adjacent to a p-bound pair, and if you can shift the two pairs.

This might help you memorise some stuff, understanding what's behind the process.

thanks a lot. its just that many times, you think of a known mechanism and try to use it to complete reaction and its dead wrong. sometimes, i dont even understand where to start.

Yeah sometimes the first idea is the wrong idea. So you're supposed to consider all the possibilities, not just go with the first thing on your mind.

>many times, you think of a known mechanism

Don't worry, it happens to organic chemists with a degree all the time too. Source: my professor.
