Vedclass · Answer

(B) The reaction of aldehydes or ketones with phenylhydrazine $(C_6H_5-NH-NH_2)$ involves the nucleophilic addition of the amine group to the carbonyl carbon followed by the elimination of a water molecule.This condensation reaction results in the formation of a phenylhydrazone.The general reaction is:$R_2C=O + H_2N-NH-C_6H_5 \rightarrow R_2C=N-NH-C_6H_5 + H_2O$Thus,the product formed is a phenylhydrazone.
