Vedclass · Answer

(D) The acidity of phenols depends on the nature of the substituents attached to the benzene ring.$1$. Electron-withdrawing groups $(EWG)$ like $-NO_2$ increase acidity by stabilizing the phenoxide ion through inductive and resonance effects.$2$. Electron-releasing groups $(ERG)$ like $-CH_3$ decrease acidity by destabilizing the phenoxide ion.$3$. In $p$-nitrophenol $(IV)$,the $-NO_2$ group at the para position exerts both $-I$ and $-M$ effects,making it the most acidic.$4$. In $m$-nitrophenol $(III)$,the $-NO_2$ group exerts only the $-I$ effect,making it less acidic than $p$-nitrophenol but more acidic than phenol.$5$. Phenol $(I)$ is the reference compound.$6$. In $p$-cresol $(II)$,the $-CH_3$ group exerts $+I$ and hyperconjugation effects,which decrease the acidity,making it the least acidic.Therefore,the correct order of acidity is $IV > III > I > II$.

In the following compounds,the order of acidity is:
$(I)$ Phenol
$(II)$ $p$-Cresol
$(III)$ $m$-Nitrophenol
$(IV)$ $p$-Nitrophenol
