This app is designed to be a complete study guide of all 100+ reactions and mechanisms which have been organized by functional group for High School, College, and University level Organic Chemistry students and for the MCAT, DAT, PCAT, OAT, GRE or any other preprofessional exam.

"Amazing application! Orgo condensed and organized by functional groups, I wish i found it before."

Simply tap a functional group and all reactions for the group appear, from there tap any reaction and see a detailed mechanism with text explanation of why it is occurring.

A simple and easy to use way of organizing all the necessary information for organic chemistry! This app can also be used as flashcards to help learn all the essential organic chemistry reactions, reagents, and mechanisms.

Crafted with love by a Harvard Organic Chemistry Student turned Physician, with the kind assistance of an Organic Chemistry PhD, and "Mutant Soup" Software.

Lots of Mechanisms - Next Step

Contains a large list of reactions, organized by reactant. It would be nice to be able to see it organized by product and a quiz-able version.

Very helpful, though.

Wouldn't have passed o chem without this app!

I have to take organic chemistry for my pharmacy curriculum and was on a slippery slope right when the first semester began. About halfway through I got this app and this thing has done WONDERS for me!! Almost every reaction my teacher has tested me on is in this app and each reaction is complete with a vivid mechanism walk through! I'm actually looking forward to my second semester hahaha... I highly recommend this app to anyone taking organic chemistry. It is a must!

Wanted to like it.

I was really excited to find this resource, so I even bought the full version. But I saw that the flashcard for the bromination of an alkene was incorrect; instead of anti-addition stereochemistry, the Br's were added on the same side. If this reaction was incorrect, how do I know the other are not, especially the ones I do not know yet. Please double check all of the reactions. You don't make studying any easier if the reactions are incorrect. I suppose its better just to make my own cards...
