Vedclass · Answer

(B) The acidity of a compound depends on the stability of its conjugate base. $1$. $Cl-CH_2-CH_2-OH$ is an aliphatic alcohol,which is much less acidic than phenols. $2$. Among the phenols,the acidity is determined by the electron-withdrawing or electron-donating nature of the substituents. $3$. The $-NO_2$ group is a strong electron-withdrawing group ($-I$ and $-M$ effect),which stabilizes the phenoxide ion significantly. $4$. The $-CH_3$ group is an electron-donating group ($+I$ and hyperconjugation),which destabilizes the phenoxide ion,making it less acidic than phenol. $5$. Therefore,$o$-Nitrophenol is the most acidic among the given options.

Which of the following compounds is the most acidic?
