Vedclass · Answer

(A) The stability of the diazonium cation is increased by electron-donating groups $(EDG)$ and decreased by electron-withdrawing groups $(EWG)$ attached to the benzene ring.$(A)$ contains $-OCH_3$,which is an $EDG$ (via resonance),thus it is the most stable.$(C)$ is the unsubstituted benzene diazonium salt.$(D)$ contains $-CN$,which is an $EWG$.$(B)$ contains $-NO_2$,which is a very strong $EWG$.Therefore,the stability order is $(A) > (C) > (D) > (B)$.

The correct stability order of the following diazonium salts is:
