Question

P-nitrochlorobenzene when reacts with caustic soda mechanism

Answer 1

Answer :-

Aryl halide experience nucleophilic displacement responses promptly when a strong el' withdrawal group i.e. nitro is available at ortho or para positions.

Whenever p - nitrochlorobenzene responds with caustic soda, p - nitrophenol is synthesized. As caustic soda is NaOH and OH group is el' donating.

Its impact is visible in given reaction. At the point when nucleophile attacks p - nitrochlorobenzene, it will make negative charge on carbon nearby nitro group which is delocalized outside of the ring and this intermediate will turn out to be more steady than chlorobenzene and thus the product for example p - nitrophenol formed.

Answer 2

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.
