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.

Assertion (A) Presence of a nitro group at ortho or para position increases the reactivity of haloarenas towards nucleophilic substitution. Reason (R ) Nitro group, being an electron withdrawing group decreases the electron density over the benzene ring.

Assertion (A) Presence of a nitro group at ortho or para position increases the reactivity of haloarenas towards nucleophilic substitution. Reason (R ) Nitro group, being an electron withdrawing group decreases the electron density over the benzene ring.

Assertion (A) : Presence of a nitro group at ortho-or para- position increases reactivity of haloarenes towards nucleophilic substitution. Reason (R) : Nitro group, being an electron withdrawing group decreases the electron density over the bvenzene ring.

The presence of electron withdrawing group increases the reactivity of haloarenes towards nuncleophilic substitution reaction. Explain.
