Chapter 20, Problem 20.4P

Interpretation Introduction

(a)

Interpretation:

The alcohol formed by the treatment of given compound with ${\text{NaBH}}_{\text{4}}{\text{ in CH}}_{\text{3}}\text{OH}$ is to be determined.

Concept introduction:

Treatment of carbonyl compounds with ${\text{NaBH}}_{\text{4}}{\text{ in CH}}_{\text{3}}\text{OH}$ yields alcohols. It is a type of reduction reaction. The reduction of an aldehyde by ${\text{NaBH}}_{\text{4}}{\text{ in CH}}_{\text{3}}\text{OH}$ yields primary alcohol and the reduction of ketone by ${\text{NaBH}}_{\text{4}}{\text{ in CH}}_{\text{3}}\text{OH}$ yield secondary alcohol.
