$o$-Nitrophenol

Vedclass · Answer

(C) The acidity of a compound depends on the stability of its conjugate base. $o$-Nitrophenol is the most acidic among the given options because the $-NO_2$ group is a strong electron-withdrawing group ($-I$ and $-M$ effect). This group stabilizes the phenoxide ion formed after the loss of a proton $(H^+)$ by dispersing the negative charge through resonance. In contrast,$-CH_3$ (in $o$-cresol) is an electron-donating group ($+I$ and hyperconjugation),which destabilizes the phenoxide ion,making it less acidic than phenol. $Cl-CH_2-CH_2-OH$ is an aliphatic alcohol,which is significantly less acidic than phenolic compounds.
