Therefore,
the presence of nitro group at meta- position does not stabilise the negative charge and
no effect on reactivity is observed by the presence of –NO2 group at meta-position Rationalised 2023-24

2 Electrophilic substitution reactions
Haloarenes undergo the usual electrophilic reactions of the benzene
ring such as halogenation, nitration, sulphonation and Friedel-Crafts
reactions Halogen atom besides being slightly deactivating is o, p-
directing; therefore, further substitution occurs at ortho- and para-
positions with respect to the halogen atom
