$OH$

Vedclass · Answer

(A) The strength of an $o,p$-directing group is determined by its ability to donate electrons to the benzene ring via the resonance effect ($+R$ or $+M$ effect).Among the given options,the $-OH$ group has a strong $+R$ effect due to the lone pairs on the oxygen atom,which are effectively donated to the ring.Halogens like $-Cl$ and $-Br$ exhibit a $-I$ effect that outweighs their $+R$ effect,making them deactivating groups,although they remain $o,p$-directing.The phenyl group $(-C_6H_5)$ is a weaker electron-donating group compared to $-OH$.Therefore,$-OH$ is the strongest $o,p$-directing group among the choices.

Which of the following is the strongest $o,p$-directing group?
