E2 Elimination: Major and Minor Products

E2 elimination reactions of alkyl halides can form one or more alkenes, and the product mix depends on regiochemistry and stereochemistry. Regiochemistry controls where the double bond appears. Stereochemistry controls the shape of the alkene that forms.

When a substrate has two different beta hy...

Elimination reactions of alkyl halides can give one or more alkenes based on specific regiochemical and stereochemical requirements.

While regiochemistry governs the location of the double bond in the product, stereochemical requirements often influence the geometry.

Consider the E2 elimination of 2-bromo-2-methyl-butane, which has...
