Chapter 9, Problem 9.68P

Interpretation Introduction

(a)

Interpretation:

For the given substrate, when $\text{NaOH}$ is used as the base, the major E2 product is to be drawn.

Concept introduction:

In an E2 reaction, the base pulls off the proton from the substrate, thus forcing the leaving group to leave. Elimination usually takes place so as to produce the most stable, meaning highly alkyl substituted, alkene. The major elimination product is the one produced by deprotonating the carbon atom initially attached to the fewest hydrogen atoms.

(b)

Interpretation:

For the given substrate, when $\text{NaOH}$ is used as the base, the major E2 product is to be drawn.

Concept introduction:

In an E2 reaction, the base pulls off the proton from the substrate, thus forcing the leaving group to leave. Elimination usually takes place so as to produce the most stable, meaning highly alkyl substituted, alkene. The major elimination product is the one produced by deprotonating the carbon atom initially attached to the fewest hydrogen atoms. In a ring with limited rotation, the leaving group has to be trans to the proton.

Interpretation Introduction

(c)
