Vedclass · Answer

(D) The acidity of phenolic compounds is determined by the stability of the phenoxide ion formed after the loss of a proton. $e-$ withdrawing groups $(EWG)$ stabilize the phenoxide ion through $-I$ and $-M$ effects,thereby increasing acidity. $p-$Nitrophenol contains a nitro group at the para position,which exerts both $-I$ and $-M$ effects,significantly stabilizing the phenoxide ion. $m-$Nitrophenol only exerts a $-I$ effect because the $-M$ effect does not operate at the meta position. $p-$Aminophenol contains an amino group,which is an $e-$ donating group ($+M$ effect),decreasing acidity. Therefore,the correct order of acidity is: $p-$Nitrophenol $ > m-$Nitrophenol $ > $ Phenol $ > p-$Aminophenol.
