Short Answer TypeGive reasons:
The presence of nitro group (–NO2) at o/p positions increases the reactivity of haloarenes towards nucleophilic substitution reactions.
The presence of nitro groups (–NO2) at o/p positions increases the reactivity of haloarenes towards nucleophilic substitution reactions because nitro groups (–NO2) at o/p positions withdraw the electron density from the benzene ring facilitating the attack of the nucleophile. The negative charge in the carbanion formed, at ortho and para positions with respect to a halogen atom, is stabilised through resonance and the presence of nitro groups (–NO2), respectively.
