I put together this summary sheet for the reaction of nucleophiles with carbonyls (click for larger image, see link to downloadable PDF below). It summarizes the two key concepts that are important to understand for these reactions: the effect of electronic and steric factors on nucleophilic addition.
I enjoyed doing this and I’d like to put together more of these types of sheets in the future. If you have suggestions for future topics, leave a comment.
