Question

When p-nitrobromobenzene reacts with sodium ethoxide, the product obtained is (A) p-nitroanisole (B) ethyl phenyl ether (C) p-nitrophenetole (D) no reaction occurs

In general aryl halides are highly stable and do not take part in Williamson's synthesis, but presence of strong electron withdrawing group like - NO 2 makes the C -X bond weaker and facilitate the substitution of - Br by - OR.

In general aryl halides are highly stable and do not take part in Williamson's synthesis, but presence of strong electron withdrawing group like −NO2​ makes the C−X bond weaker and facilitate the substitution of −Br by −OR.
