Oh, organic chemistry reaction mechanisms… They are indeed the bane of many a student’s existence. Yet, they may not be quite so painful if you have the Organic Chemistry! Complete app. This app organizes the major organic chemistry reactions by chemical class (alcohols, alkynes, etc.), displaying each class on the app’s home screen as a notecard pinned to a corkboard background. Clicking on one of these “notecards” displays an overview of all of the reactions contained within that group. In turn, each of these reactions can be selected to display the actual electron-pushing reaction mechanism diagrams. (Note that there is a free version of this app, but it does not include reaction mechanisms.) The reaction mechanism diagrams contain some annotation, but they would benefit from more detail.
