Question

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.

Options

  • Assertion and reason both are correct and reason is correct explanation of assertion.

  • Assertion and reason both are wrong statements.

  • Assertion is correct but reason is wrong statement.

  • Assertion is wrong but reason is correct statement.

  • Assertion and reason both are correct statements but reason is not correct explanation of assertion.

Solution

Assertion and reason both are correct and reason is correct explanation of assertion.

Explanation:

Nitro group being electron withdrawing group, decreases the electron density of ring hence increase the reactivity of haloarenes towards nucleophilic substitution.
