Vedclass · Answer

(C) The acidic strength of phenols depends on the nature of the substituent attached to the benzene ring.Electron-withdrawing groups $(EWG)$ like $-NO_2$ stabilize the phenoxide ion through resonance and inductive effects,thereby increasing acidic strength.Electron-donating groups $(EDG)$ like $-OCH_3$ and $-CH_3$ destabilize the phenoxide ion by increasing electron density.The $-OCH_3$ group acts as an $EDG$ via the $+M$ effect,which is stronger than the $+I$ effect of the $-CH_3$ group,making $p-$methoxy phenol less acidic than $p-$methyl phenol.Thus,the order of acidic strength is: $p-$methoxy phenol $(i)$ The correct increasing order is $i < ii < iii$.

What is the increasing order of acidic strength among the following?
$(i)$ $p-$methoxy phenol
$(ii)$ $p-$methyl phenol
$(iii)$ $p-$nitro phenol
