Write short note on Wolf-Kishner reaction.

Explanation

Wolf-kishner reduction. In this reduction aldehydes or ketones are reduced to hydrocarbonds with hydrazine `(H_(2)N - NH_(2))` and KOH.
`underset("Acetaldehyde")(CH_(3)-overset(H)overset(|)(C)=O) + H_(2)N - NH_(2) underset(-H_(2)O)rarr CH_(3)-overset(H)overset(|)(C)=N-NH_(2) overset(KOH//470K)rarr underset("Ethane")(CH_(3)-CH_(3)+N_(2))`
`underset("Acetone")(CH_(3)-overset(CH_(3))overset(|)(C)=O) + H_(2)N - NH_(2) underset(-H_(2)O)rarr CH_(3)-overset(CH_(3))overset(|)(C)=N-NH_(2) overset(KOH//470K)rarr underset("Propane")(CH_(3)-CH_(2)-CH_(3)+N_(2))`
