Question

diazonium salts of aromatic amines are more stable than those of aliphatic amines

Answer 1

The diazonium ion undergoes resonance.This resonance accounts for the stability of the diazonium ion.Hence,diazonium salts of aromatic amines are more stable than those of aliphatic amines.

Answer 2

Due to resonance there is a dispersal of positive charge on the benzene ring. This resonance accounts for the stability of the diazonium ion. Hence, diazonium salts of aromatic amines are more stable than those of aliphatic amines.
