Question

Quizplus · Accepted Answer

Only compound II has a carbonyl group (C=O) attached to a secondary amine, which will not undergo the necessary hydrolysis reaction to yield nicotinamide when reacted with ammonia at room temperature. The other compounds (I, III, and IV) all have primary or tertiary amine groups directly attached to the pyridine ring, which will undergo hydrolysis to yield nicotinamide.
