Vedclass · Answer

(D) The acidity of a compound depends on the stability of its conjugate base. $1$. Acetic acid $(CH_3COOH)$ is a carboxylic acid,and its conjugate base (acetate ion) is stabilized by resonance between two equivalent oxygen atoms,making it more acidic than phenol ($pK_a \approx 4.75$ vs $pK_a \approx 10$). $2$. $p-$nitrophenol is more acidic than phenol because the nitro group $(-NO_2)$ exerts a strong electron-withdrawing effect ($-I$ and $-M$ effects),which stabilizes the phenoxide ion. Therefore,phenol is less acidic than both acetic acid and $p-$nitrophenol.
