Interpretation Introduction

Interpretation: The stereochemistry of the product form by the reaction between given ketone and sodium borohydride $\left({\text{NaBH}}_{\text{4}}\right)$ needs to be predicted.

Concept Introduction: The sodium borohydride $\left({\text{NaBH}}_{\text{4}}\right)$ is a strong reducing agent and it reduces carbonyl compounds (aldehydes and ketones) and produces alcohol. The hydrogen in sodium borohydride is negatively charge and called hydride. And the nucleophilic attack of hydride on the carbonyl carbon form alcohol.
