The Wolff-Kishner reaction involves the reaction of an aldehyde/ketone with hydrazine in the presence of KOH. The process is useful for converting an aldehyde or ketone into an alkane. The reaction involves formation of a hydr followed by base-catalyzed double-bond migration, loss of N₂ gas to give a carbanion, and protonation to give the alkane. Draw curved arrows to show the movement of electrons in this step of the mechanism.

The Wolff-Kishner reaction involves the reaction of an aldehyde/ketone with hydrazine in the presence of KOH. The process is useful for converting an aldehyde or ketone into an alkane. The reaction involves formation of a hydrazone,
followed by base-catalyzed double-bond migration, loss of N₂ gas to give a carbanion, and protonation to give the alkane.
