Question

Draw the products formed (including stereoisomers) when each compound is reduced with NaBH₄in CH₃OH.

Short answer

Answer

The products formed when each compound is treated with NaBH₄ in CH₃OH. are shown below:

Step-by-step solution

Step-by-Step Solution Step 1: Function of  NaBH4

NaBH₄ is a strong reducing agent that reduces ketone into secondary alcohol and aldehyde into primary alcohol.

Since chiral alcohol is formed after reduction, hence two kinds of alcohols are formed. They are collectively called enantiomeric alcohols.

Mechanism of the reducing action of  NaBH4

In NaBH₄ , B-H is weakly polar where the hydride group acts as a nucleophile and can readily attack the carbonyl carbon center to yield alcohol.

Hence, based on the explanations, the products formed when each compound is treated with NaBH₄in CH₃OH are shown below:
