Vedclass · Answer

(C) To determine the acidity,we compare the stability of the conjugate base formed after the loss of a proton $(H^+)$.$1$. $p$-Nitrophenol is a phenol derivative,which is generally less acidic than carboxylic acids.$2$. Among the carboxylic acids ($p$-Hydroxybenzoic acid,$o$-Hydroxybenzoic acid,and $p$-Toluic acid),the acidity depends on the inductive and resonance effects of the substituents.$3$. $o$-Hydroxybenzoic acid (Salicylic acid) exhibits the ortho effect and intramolecular hydrogen bonding,which stabilizes the carboxylate anion significantly.$4$. Comparing the substituents: $-OH$ at the ortho position in $o$-hydroxybenzoic acid provides strong stabilization compared to the para position in $p$-hydroxybenzoic acid due to the proximity of the hydroxyl group to the carboxylate group.$5$. Therefore,$o$-Hydroxybenzoic acid is the most acidic among the given options.
