The correct stability order of the following diazonium salts is
Options
- AC > A > D > B
- BA > C > D > B
- CA > B > C > D
- DC > D > B > A
Correct answer
B. A > C > D > B
Step-by-step solution
The stability of benzenediazonium salts is governed by the electronic effects of the substituents present on the benzene ring. The diazonium group -N₂^+ is strongly electron-withdrawing. Electron-donating groups (EDG) stabilize the diazonium cation by dispersing the positive charge through resonance or inductive effects, whereas electron-withdrawing groups (EWG) destabilize it by increasing the positive charge density. In (A), the -OCH₃ group at the para position is a strong electron-donating group via the +M effec
