$2-$methylphenol

Vedclass · Answer

(C) In electrophilic aromatic substitution,the incoming electrophile attacks the position that is ortho or para to the most strongly activating group (the group with the strongest electron-releasing effect).For $2$-methylphenol ($o$-cresol),the $-OH$ group is a much stronger activating group than the $-CH_3$ group.The $-OH$ group directs the electrophile to its ortho and para positions.The para position with respect to the $-OH$ group is the meta position with respect to the $-CH_3$ group.Therefore,halogenation of $2$-methylphenol yields the $m$-substituted product with respect to the methyl group as the major product.

List-$I$ (Compound)	List-$II$ ($pK_a$ value)
$A$. Ethanol	$I$. $10.0$
$B$. Phenol	$II$. $15.9$
$C$. $m$-Nitrophenol	$III$. $7.1$
$D$. $p$-Nitrophenol	$IV$. $8.3$
