Vedclass · Answer

(A) The stability of benzene diazonium salts is influenced by the nature of the substituent attached to the benzene ring.Electron-donating groups $(EDG)$ increase the stability of the diazonium cation by dispersing the positive charge,while electron-withdrawing groups $(EWG)$ decrease the stability by intensifying the positive charge.In the given compounds:$A$: $-OCH_3$ is a strong $EDG$ ($+M$ effect).$C$: Benzene diazonium chloride (no substituent).$D$: $-CN$ is an $EWG$ ($-M$ effect).$B$: $-NO_2$ is a very strong $EWG$ ($-M$ effect).Therefore,the stability order is $A > C > D > B$.

The correct stability order of the following diazonium salts is:
