Vedclass · Answer

(D) Acidity depends on the stability of the conjugate base. Carboxylic acids ($D$ and $E$) are stronger acids than phenols $(A, B, C)$.Between $4$-nitrobenzoic acid $(D)$ and benzoic acid $(E)$, the $-NO_2$ group (strong electron-withdrawing) makes $D$ stronger.Among phenols, $4$-nitrophenol $(B)$ is the strongest due to the electron-withdrawing $-NO_2$ group, followed by phenol $(A)$, and $4$-methoxyphenol $(C)$ is the weakest due to the electron-donating $-OCH_3$ group.Thus, the descending order of acidity is $D > E > B > A > C$.

The descending order of acidity among the following compounds is:
