The assertion (A) is incorrect while the reason (R) is correct. Diazonium salts of aliphatic amines are less stable than those of aromatic amines. This is because aromatic amines form a stable complex due to resonance, which is not possible in aliphatic amines.

Step by Step Explanation:

1. Diazonium salts are formed by the reaction of nitrous acid with amines.

2. In the case of aromatic amines, the positive charge on the nitrogen atom of the diazonium salt is delocalized into the benzene ring. This delocalization or resonance provides extra stability to the diazonium salt.

3. On the other hand, aliphatic amines do not have a system of delocalized electrons, so the positive charge on the nitrogen atom is not delocalized. This makes diazonium salts of aliphatic amines less stable than those of aromatic amines.

4. Therefore, the assertion that diazonium salts of aliphatic amines are more stable than those of aromatic amines is incorrect. However, the reason that diazonium salts of aromatic amines show resonance is correct.
