Chapter 8, Problem 8.14P

Interpretation Introduction

Interpretation:

The complete, detailed mechanism for the reaction is to be drawn assuming it proceeds via an $\text{E1}$ mechanism, paying attention to stereochemistry.

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. An $\text{E1}$ reaction produces a mixture of the E and Z configurations about a double bond formed in the products.
