Chapter 20, Problem 20.8P

Interpretation Introduction

(a)

Interpretation:

The products formed (including stereoisomers) by the reduction of given compound with ${\text{NaBH}}_{\text{4}}$ and ${\text{CH}}_{\text{3}}\text{OH}$ is to be drawn.

Concept introduction:

Treatment of carbonyl compounds with ${\text{NaBH}}_{\text{4}}{\text{ and CH}}_{\text{3}}\text{OH}$ yields alcohols with stereogenic carbon. Reduction converts a planar $s{p}^2$ hybridized carbonyl carbon to $s{p}^3$ hybridized carbon with a new stereogenic centre.

Interpretation Introduction

(b)

Interpretation:

The products formed (including stereoisomers) by the reduction of given compound with ${\text{NaBH}}_{\text{4}}$ and ${\text{CH}}_{\text{3}}\text{OH}$ is to be drawn.

Concept introduction:

Treatment of carbonyl compounds with ${\text{NaBH}}_{\text{4}}{\text{ and CH}}_{\text{3}}\text{OH}$ yields alcohols with stereogenic carbon. Reduction converts a planar $s{p}^2$ hybridized carbonyl carbon to $s{p}^3$ hybridized carbon with a new stereogenic centre.

Interpretation Introduction

(c)
