Question

Give reasons :

Aromatic diazonium salts are more stable than aliphatic diazonium salts.

Answer 1

Due to resonance stabilisation or structural representation / resonating structures.

Detailed Answer :

Aromatic diazonium salts are more stable than aliphatic diazonium salts due to dispersion of positive charge over the benzene ring caused by resonance. This is  not found in aliphatic diazonium salts.
