Nucleophilic addition-elimination mechanism

Vedclass · Answer

(D) The reaction of a carbonyl compound (cyclopentanone) with hydrazine $(H_2N-NH_2)$ in the presence of an acid catalyst $(H^+)$ is a classic example of nucleophilic addition followed by elimination of a water molecule.$1$. The nucleophilic nitrogen atom of hydrazine attacks the electrophilic carbonyl carbon of the ketone.$2$. This is followed by proton transfer and the elimination of a water molecule $(H_2O)$ to form a hydrazone.$3$. Therefore,the overall mechanism is classified as a nucleophilic addition-elimination reaction.
