Account for the following.
Diazonium salts of aromatic amines are more stable than those of aliphatic amines.

उत्तर
Diazonium salts of aromatic amines are stabilized by resonance with the aromatic ring, allowing the positive charge on the nitrogen to be delocalized into the ring. The delocalization enhances the stability of the diazonium ion. Conversely, aliphatic amines lack this resonance stabilization, resulting in their diazonium salts being less stable and more susceptible to breakdown. Resonance in diazonium salt, as shown below.
