JEE Main levelSingle correct optionDifficulty 2 of 3o1078

4-Methylacetophenone, $p - CH X_{3} - C X_{6} H X_{4} - CO - CH X_{3}$ , is heated with $NH X_{2} NH X_{2}$ and KOH in ethylene glycol. The product is

A1-(4-methylphenyl)ethan-1-amine
B1-(4-methylphenyl)ethan-1-ol
C4-methylbenzoic acid
D1-ethyl-4-methylbenzene

Answer: D

Wolff-Kishner reduction converts the carbonyl group via its hydrazone into

CH X_{2}

with loss of

N X_{2}

, giving the ethyl group. The ring methyl is unaffected.
