$3-$nitrobenzoic acid

Vedclass · Answer

(D) The acidic strength of substituted benzoic acids is primarily influenced by the inductive effect $(-I)$ of the substituent group at the meta position.Acidic strength is directly proportional to the electron-withdrawing nature of the substituent ($-I$ effect).Comparing the substituents at the meta position:$1$. $-OH$ group: Shows $-I$ effect but also $+M$ effect.$2$. $-Cl$ group: Shows $-I$ effect.$3$. $-CH_3$ group: Shows $+I$ effect (decreases acidity).$4$. $-NO_2$ group: Shows a strong $-I$ effect.Since the $-NO_2$ group has the strongest electron-withdrawing inductive effect among the given options,$3$-nitrobenzoic acid is the most acidic compound.
