Question
Account for the following:
Diazonium ions of aromatic amines are more stable than those of aliphatic amines.
Solution
Primary aliphatic amines form a highly unstable alkyl diazonium salts. Primary aromatic amines form arene diazonium salts which are stable for a short time in solution at low temperature (273— 278 K). The stability of diazonium ions of aromatic amines is explained on the basis of resonance.
