$4-$Nitrobenzoic acid

Vedclass · Answer

(D) is the correct answer.Acidic strength of benzoic acid derivatives is increased by electron-withdrawing groups $(EWG)$ and decreased by electron-donating groups $(EDG)$.$4-$Nitrobenzoic acid contains a $-NO_2$ group,which is a strong electron-withdrawing group ($-I$ and $-M$ effect),thereby stabilizing the carboxylate anion and increasing acidity.$2-$Methoxybenzoic acid and $4-$Methoxybenzoic acid contain a $-OCH_3$ group,which acts as an electron-donating group ($+M$ effect),decreasing the acidic strength compared to benzoic acid.Therefore,$4-$Nitrobenzoic acid has the maximum acidic strength among the given options.
