Question

Give proper reaction

Answer 1

Answer:

The mechanism of nucleophilic substitution when p-Nitro Chlorobenzene is treated with caustic soda: Electron withdrawing group activates the Benzene to nucleophilic attack. NaOH will react with chlorobenzene, but solely underneath extreme conditions. Aryl halides cannot endure an electron withdrawing groups ortho and para to the leaving group activate the ring to nucleophilic attack. The presence of additional electron withdrawing group increases the rate of the reaction.

Answer 2

Para Nitro phenol is formed.

Nucleophilic Substitution reactivity of Chloronenzene can be increased by introducing a strong electron withdrawing group such as NO2 at orthor or para positions.

If u think why only ortho and para position ———

The NO2 can stabilise the compound if present in ortho para position because it can withdraw negative charges present at these positions due to its resonance.

The attack of the nucleophile (OH^-) results in a CARBANION intermediate.
