Chapter 10, Problem 10.21P

Interpretation Introduction

(a)

Interpretation:

The absolute configuration of the alkyl chloride obtained from the reaction of thionyl chloride with $\left(S\right){\text{-CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{CHD}-\text{OH}$ is to be stated.

Concept introduction:

The nucleophilic substitution reactions are the reactions in which one nucleophile is substituted by the another nucleophile. These reactions depend upon the nucleophilicity and concentration of the incoming nucleophile.

The ${\text{S}}_{\text{N}}\text{2}$ reaction is a nucleophilic substitution bimolecular single step reaction in which the addition of incoming nucleophile and removal of outgoing nucleophile takes place simultaneously.

Interpretation Introduction

(b)

Interpretation:

The absolute configuration of $\text{2-bromopentane}$ obtained from the reaction of ${\text{Ph}}_{\text{3}}{\text{PBr}}_{\text{2}}$ with the R enantiomer of $\text{2-pentanol}$ is to be stated.
