Interpretation Introduction

(a)

Interpretation: The epoxide that is needed to convert ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{MgBr}$ to given alcohol, after quenching with water is to be predicted.

Concept introduction: Organometallic reagents like $\text{RLi,}\text{RMgX}$ and ${\text{R}}_{\text{2}}\text{CuLi}$ are the source of ${\text{R}}^{-}$, which acts as a nucleophile. Epoxide converts into alcohol on treatment with organometallic reagents.
