Q. In Wolff‐Kishner reduction, the carbonyl group of aldehydes and ketones is converted into

AIIMSAIIMS 1994Aldehydes Ketones and Carboxylic Acids

Solution:

Wolf - Kishner reduction :

Aldehyde and Ketones are reduced to hydrocarbons in the presence of excess of hydrazine and strong base on heating.

$R - \underset{\underset{H}{|}}{C} = O + H _{2} N NH _{2} \xrightarrow[{200^{\circ} C }]{{ KOH }} R - \underset{\underset{H}{|}}{C}H _{2}+ N _{2}+ H _{2} O$
