Vedclass · Answer

(A) Nucleophilic addition-elimination reactions involve the addition of a nucleophile to the carbonyl carbon followed by the elimination of a water molecule. In the reaction of $CH_3CHO$ with $NaHSO_3$,the bisulfite ion acts as a nucleophile and adds to the carbonyl carbon to form a bisulfite addition product. This is a pure nucleophilic addition reaction,not an addition-elimination reaction,as no water molecule is eliminated. Options $B$,$C$,and $D$ represent the formation of oximes,hydrazones,and imines respectively,which are classic examples of nucleophilic addition-elimination reactions.

Which of the following reactions is not an example of a nucleophilic addition-elimination reaction?
