Chapter 9, Problem 9.19P

Interpretation Introduction

Interpretation:

The substrate that undergoes $\text{E1}$ reaction faster is to be identified.

Concept introduction:

The rate of $\text{E1}$ reaction depends on the stability of the carbocation formed in the rate-determining step. In the rate-determining step, the formation of carbocation is takes place by the departure of the leaving group via the heterolysis step. As the number of alkyl groups on the carbon bonded to the leaving group increases, the rate of $\text{E1}$ reaction increases.
