Correct answer
D
Step-by-step explanation
Cyclohexylmethylamine reacts with benzoyl chloride under basic conditions to form amide [A]:
cyclohexylmethyl benzoamide.
LiAlH₄ reduces the amide carbonyl to CH₂, converting the N-benzoyl group to a benzyl group.
The product [B] is a secondary amine formed by reduction:
cyclohexylmethyl-benzylamine ().
This structure contains secondary amine (N-H) with two carbon substituents: cyclohexylmethyl and benzyl groups.
cyclohexylmethyl benzoamide.
