Vedclass · Answer

(A) The Wolff-Kishner reduction is a chemical reaction used to convert carbonyl groups (aldehydes or ketones) into methylene groups $(-CH_2-)$. It involves heating the carbonyl compound with hydrazine $(NH_2NH_2)$ and a strong base like potassium hydroxide $(KOH)$ in a high-boiling solvent such as ethylene glycol. The reaction proceeds via the formation of a hydrazone intermediate,which then undergoes base-catalyzed decomposition to release nitrogen gas $(N_2)$ and form the corresponding alkane.

The reagent used in the Wolff-Kishner reduction is
