Vedclass · Answer

(B) Groups that exert a $-I$ effect (electron-withdrawing) but are $o, p$-directing due to the $+M$ or $+R$ effect are typically halogens.In the case of $-Cl$,the electronegativity causes a $-I$ effect,but the lone pair of electrons on the chlorine atom allows for resonance ($+R$ effect),which increases electron density at the ortho and para positions.Therefore,$-Cl$ is deactivating but $o, p$-directing.

Which of the following groups acts as both $-I$ effect and $o, p$-directing group?
