Interpretation Introduction

(a)

Interpretation:

The mechanism of conversion of enantiomerically pure $\left(R\right){\text{-CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{CHD}-\text{OH}$ into $\left(S\right){\text{-CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{CHD}{-}^{18}\text{OH}$ is to be stated.

Concept introduction:

Substitution reaction is one of the types of reaction in which one species is replaced by the other species. Substitution reactions can be done either by ${\text{SN}}_1$ mechanism or by ${\text{SN}}_2$ mechanism. Inversion of the stereochemistry of the product from reactant takes place in ${\text{SN}}_2$ mechanism.
