Assertion: Presence of a nitro group at ortho or para position increases the reactivity of haloarenes towards nucleophilic substitution.
Reason : Nitro group, being an electron withdrawing group decreases the electron density over the benzene ring.
(i) Assertion and reason both are correct and reason is correct explanation of assertion.
(ii) Assertion and reason both are wrong statements.
(iii) Assertion is correct but reason is wrong statement.
(iv) Assertion is wrong but reason is correct statement.
(v) Assertion and reason both are correct statements but reason is not correct explanation of assertion.

This is a assertion and reason answer type question as classified in NCERT Exemplar
The nitro group on the ortho and para positions of haloarenes acts as an electron-withdrawing group, making it more reactive to nucleophilic substitution reactions due to the electron deficit.
