Chapter 9, Problem 100P

(a)

Interpretation Introduction

Interpretation:

The structures of products obtained from the reaction of $\text{cis-1-chloro-2-isopropylcyclopentane}$ with sodium methoxide in methanol should be drawn.

Concept Introduction:

The ${\text{S}}_{\text{N}}\text{2 }$ reaction is a type of reaction mechanism in which one bond is broken and one bond is formed i.e., in one step.${\text{S}}_{\text{N}}\text{2 }$ is a kind of nucleophilic substitution reaction mechanism.

An $\text{E2}$ reaction is a concerted, one-step reaction in which the proton and the halide ion are removed in the same step.

(b)

Interpretation Introduction

Interpretation:

The optically activity of products obtained from the reaction of $\text{cis-1-chloro-2-isopropylcyclopentane}$ with sodium methoxide in methanol should be explained.

An E2 reaction is a concerted, one-step reaction in which the proton and the halide ion are removed in the same step.

(c)

Interpretation Introduction

Interpretation:

How would be the products differ if the starting material were the Trans isomer should be explained and the optical activity of products obtained from the Trans isomer should be explained.

Interpretation Introduction

Interpretation:

The rate of formation of substitution products should be comparatively explained, where the cis and Trans isomers of 1-chloro-2-isopropylcyclopentan of with sodium methoxide in methanol.
