Question

In the addition reaction of ammonia derivatives ($NH_2-Z$) with carbonyls, what happens if the medium is rendered too highly acidic (pH < 3)?

Answer: C

💡 Solution & Explanation

If the pH is too low, the lone pair on the nitrogen of the weak nucleophile is protonated (forming $NH_3^+-Z$), rendering it completely incapable of nucleophilic attack.
