Vedclass · Answer

(D) The acidity of phenols is determined by the stability of the phenoxide ion formed after the loss of a proton.Electron-withdrawing groups $(EWG)$ like $-NO_2$ increase acidity by stabilizing the negative charge through inductive $(-I)$ and resonance $(-M)$ effects.Electron-donating groups $(EDG)$ like $-CH_3$ decrease acidity by destabilizing the negative charge through inductive $(+I)$ and hyperconjugation effects.$(IV)$ $p$-Nitrophenol: The $-NO_2$ group at the para position exerts both $-I$ and $-M$ effects,making it the most acidic.$(III)$ $m$-Nitrophenol: The $-NO_2$ group at the meta position exerts only the $-I$ effect,making it less acidic than the para isomer but more acidic than phenol.$(I)$ Phenol: Acts as the reference compound.$(II)$ $p$-Cresol: The $-CH_3$ group at the para position is an $EDG$,which decreases the acidity compared to phenol.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
