Vedclass · Answer

(C) The acidic strength of phenol is determined by the stability of the phenoxide ion formed after the loss of a proton. Electron-withdrawing groups ($-I$ or $-M$ effect) increase the acidic strength by stabilizing the phenoxide ion. Electron-donating groups ($+I$ or $+M$ effect) decrease the acidic strength by destabilizing the phenoxide ion. Among the given options,$-NO_2$,$-CN$,and $-CHO$ are electron-withdrawing groups,whereas $-CH_3$ exhibits a $+I$ (inductive) effect,which increases electron density on the ring and destabilizes the phenoxide ion,thereby decreasing the acidic strength.

Which of the following substituents will decrease the acidic strength of phenol?
