The Big Daddy Flowchart (Determining Mechanisms)

Here is the best flowchart you’ll ever learn in your life. Seriously.

Professors rarely tell you which mechanisms to use. Instead, they’ll give you a set of reagents and ask you to figure it out yourself. This flowchart basically explains that entire process. Let’s go! 

Determining Mechanisms

When do you use this flowchart? Whenever you have a nucleophile and a GOOD leaving group. 

In general, the left side of the flowchart predicts SN2 /E2 mechanisms, and the right side predicts SN1/E1 mechanisms, but there are exceptions.
