Chapter 8, Problem 8.23P

Interpretation Introduction

Interpretation:

A reasonable mechanism for the given elimination reaction is to be given assuming that it takes place via an $\text{E1}$ mechanism.

Concept introduction:

$\text{E1}$ reaction is a unimolecular elimination reaction which takes place in two steps. In the first step, the bond between the carbon atom and the leaving group breaks to generate a carbocation, which is known as a heterolysis step. In the second step, a base removes a proton forming an alkene. A proton transfer reaction is handy and can be incorporated in the mechanism of an $\text{E1}$ elimination to avoid the formation of incompatible species.
