All of the above

Vedclass · Answer

(D) The acidity of phenol is directly proportional to the electron-withdrawing effect ($-I$ and $-M$ effect) of the substituent attached to the benzene ring.All the given groups,$-NO_2$,$-CN$,and $-CHO$,are electron-withdrawing groups $(EWG)$ that stabilize the phenoxide ion by dispersing the negative charge through $-I$ and $-M$ effects.Therefore,all of these groups increase the acidity of phenol.
