Chapter 8, Problem 8.16P
Interpretation Introduction

(a)

Interpretation:

The product with greater abundance in the given E1 reaction is to be predicted.

Concept introduction:

The E1 reaction proceeds with the formation of a carbocation intermediate by elimination of the leaving group in the first step. In the second step, the hydrogen atom adjacent to the carbocation is removed by the base to form a double bond. As the carbocation is planar, the elimination product would be a mixture of diastereomers when the double bonded carbon atoms are asymmetrically substituted. The stereochemistry of C=C bond is indicated by E/Z notation. E represents the trans double bond. When the same priority groups are on opposite side of the double bond, the representation E is used. Z represents the cis double bond. When the same priority groups are on the same side of the double bond., the representation Z is used. The isomer with the bulkier groups on opposite side of C=C bond is more stable due to less steric hindrance.
