Vedclass · Answer

(A) The acidity of compounds depends on the stability of the conjugate base formed after the loss of a proton $(H^+)$.$1$. $p-$Nitrophenol $(A)$: The nitro group $(-NO_2)$ is a strong electron-withdrawing group ($-I$ and $-M$ effect),which stabilizes the phenoxide ion significantly,making it the most acidic. Its $pK_a$ is $7.1$ $(I)$.$2$. Phenol $(B)$: Phenol is more acidic than ethanol but less acidic than $p-$nitrophenol. Its $pK_a$ is $10.0$ $(II)$.$3$. Ethanol $(C)$: Aliphatic alcohols are much less acidic than phenols due to the electron-donating alkyl group ($+I$ effect) which destabilizes the alkoxide ion. Its $pK_a$ is $15.9$ $(III)$.$4$. $p-$Cresol $(D)$: The methyl group $(-CH_3)$ is an electron-donating group ($+I$ and hyperconjugation),which destabilizes the phenoxide ion compared to phenol,making it less acidic. Its $pK_a$ is $10.2$ $(IV)$.Therefore,the correct matching is $A-I, B-II, C-III, D-IV$.
