Carbonyl compounds are reduced to alcohols by hydride reagents. This reduction involves

Options

A. addition of two hydrogens across a `C=O` bond
B. reduction of carbonyl group to an alkoxide which is protonated to alcohol
C. Both (a) and (b)
D. None of the above

Answer

C

Explanation

The given reduction involves addition of two hydrogens across `C=O` bond and reduction of carbonly group to an alkoxide which is protonated to alcohol.

The reduction of the carbonyl group by `LiAlH_(4) or NaBH_(4)` occurs as follows.
