$-N=O$

Vedclass · Answer

(A) The substituent $-N=O$ (nitroso group) is deactivating because of its strong $-I$ effect,which withdraws electron density from the benzene ring.However,it is ortho-para directing because the nitrogen atom possesses a lone pair of electrons that can be delocalized into the ring via the $+M$ (mesomeric) effect.This $+M$ effect increases electron density specifically at the ortho and para positions,directing electrophilic substitution to these sites.

Which of the following benzene ring substituents is deactivating but ortho-para directing?
