Question

Diazonium salts of aliphatic amines are more stable than those of aromatic amines.
If this is true enter 1, if false enter 0.

Answer 1

Aliphatic amines form highly unstable alkyldiazonium salts. Primary aromatic amines form arenediazonium salts which are stable for a short time in solution at low temperatures (273-278 K). The stability of arenediazonium ion is explained on the basis of resonance.

It has four resonating structure which makes them very stable.
