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.
