How to Predict the Stereochemistry Outcome of an E2 Reaction Help Me With Organic Chemistry!

The E2 reaction delivers alkene products. A reaction that follows an E2 mechanism becomes interesting when there are stereocenters that can deliver two diastereomers known as E or Z (cis or trans. The outcome of an E2 reaction is entirely predictable when you follow the rules. In this video I will show you how to use Newman projections to predict the E or Z cis or trans out come of these reactions. I will also show you how to do this without using a Newman Projection and get the same result!

The E2 mechanism is second order. This means that the base and the substrate exist together in the transition state of the rate determining step.

This video is part of a series called How to be Successful in Organic Chemistry. In this series I go over numerous problems that a student could expect to see in there organic chemistry 1 course. Doing organic chemistry practice problems will make you more successful in organic chemistry and biochemistry.

I recommend that you download the problem from the link below and attempt the problem yourself and use this video to correct your work.
