Vedclass · Answer

(B) The $-NO_2$ group is a strong electron-withdrawing group due to its $-I$ and $-M$ effects. It decreases the electron density at the ortho and para positions of the benzene ring. Therefore,the incoming electrophile (nitronium ion,$NO_2^+$) is directed to the meta-position,where the electron density is relatively higher compared to the ortho and para positions. Thus,$m$-dinitrobenzene is obtained.
