Chapter 20, Problem 20.36P

Interpretation Introduction

(a)

Interpretation: The products formed by the treatment of ${\text{NaBH}}_{\text{4}}\text{,}{\text{CH}}_{\text{3}}\text{OH}$ with compound A and B are to be drawn.

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. Ketones on reaction with Grignard reagent converts into tertiary alcohol whereas aldehydes give primary and secondary alcohol.

Interpretation Introduction

(b)

Interpretation: The products formed by the treatment of ${\text{LiAlH}}_{\text{4}}\text{,}{\text{H}}_{\text{2}}\text{O}$ with compound A and B are to be drawn.

Interpretation Introduction

(c)

Interpretation: The products formed by the treatment of ${\text{CH}}_3\text{MgBr,}{\text{H}}_{\text{2}}\text{O}$ with compound A and B are to be drawn.
