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

NTA AbhyasNTA Abhyas 2020Aldehydes Ketones and Carboxylic Acids

Solution:

Wolf kischner reduction : Hydrazine $\left(\right.NH_{2}-NH_{2}\left.\right)$ followed by reaction with strong base like $KOH$ reduce carbonyl group into alkyl group.

$\underset{C a r b o n y l \, g r o u p}{> C = O}+\underset{H y d r a z i n e}{N H_{2}}-NH_{2}\overset{W o l f - K i s h n e r}{ \rightarrow }>C=N-NH_{2}\overset{K O H}{ \rightarrow }>\underset{A l k y l \, g r o u p}{C H_{2}}$
