So, most of you are probably just starting your organic chemistry II lectures rights now.  It might be a little early to introduce this site, but it is definitlely one of my favs.  It is run by THE (emphasis added) Ohio State University, and consists of organic chemistry flash cards.   I have gone thru them all and they are a great resource.  Check it out, it will be a big help for all undergrad o-chem student.

Good luck and happy reacting.
