Question

Wolff-Kishner reduction is:

• A. reduction of carbonyl compounds into hydrocarbon
• B. reduction of carbonyl compounds into alcohols
• C. reduction of nitrobenzene into aniline
• D. reduction of carbohydrates into alcohols

Answer 1

The correct option is A reduction of carbonyl compounds into hydrocarbon

The carbonyl group of aldehydes and ketones is reduced to $C{H}_2$ group (hydrocarbons) on treatment with hydrazine followed by heating with sodium or potassium hydroxide in high boiling solvent such as ethylene glycol is known as Wolff-Kishner reduction.
Mechanism of simple Wolff-kishner reductions are given below:

So, the correct option is (a).
