Vedclass · Answer

(D) The acidic strength depends on the stability of the conjugate base formed after the loss of a proton $(H^+)$.$1.$ Phenol $(I)$ is much less acidic than carboxylic acids $(II, III, IV)$.$2.$ Among the carboxylic acids,electron-withdrawing groups $(-NO_2)$ increase acidity,while electron-donating groups $(-CH_3)$ decrease it.$3.$ Compound $II$ ($p$-nitrobenzoic acid) has a strong $-I$ and $-M$ effect,making it the most acidic.$4.$ Compound $III$ (benzoic acid) is the reference.$5.$ Compound $IV$ ($p$-toluic acid) has a $+I$ and $+H$ effect,making it the least acidic among the carboxylic acids.$6.$ Therefore,the order is $II > III > IV > I$.

The correct order of acidic character of the following compounds is:
