Interpretation Introduction

Interpretation:

The major alkene product has to be identified by following E₁ reaction.

Concept introduction:

Elimination reaction:

An elimination reaction is removal of two substituents in a molecule and forms alkene. An elimination reaction is one or two-step process which based on the mechanism when two substituents removed from the molecule in single step is called E₂ reaction. When two substituents are removed from the molecule in two steps is called E₁ reaction.

E₁ elimination:

Alkyl halide forms carbocation by the removal of bromine followed by the abstraction of the proton from the β-carbon atom in two steps which leads to the product as an alkene.

Saytzeff's Rule:

It is elimination reaction in which the formation of olefin on most hindered or highly substituted position.
