Question
**Question:**

a) What does "E2" stand for in an E2 reaction?

b) What kind of geometry is absolutely necessary for an E2 reaction to occur? Draw an example.

**Answer Explanation:**

E2 stands for bimolecular elimination. It is a type of elimination reaction where the removal of a hydrogen and a leaving group happens simultaneously in a single concerted step. For an E2 reaction to occur, an antiperiplanar geometry is essential. This means that the hydrogen atom and the leaving group must be on opposite sides of the molecule in the same plane to allow for effective orbital overlap during the transition state.

A classic example is the elimination of HBr from alkyl halides in the presence of a strong base, resulting in the formation of alkenes.
