Give plausible explanation for each of the following: There are two –NH 2 groups in semicarbazide. However, only one is involved in the formation of semicarbazones.

Question

Philoid · Accepted Answer

Only one Amino group is involved in the resonance structure of semicarbazide hence e^- density on NH₂ group decreases & it can’t act as a nucleophile. But another NH₂ group can attack as a nucleophile to form semicarbazones.
