Chemistry - Aromatic Hydrocarbon Question with Solution | TestHub

Question Explanation:

Question is asking about major products for the given S_NAr reaction.

Concept:   This question is based on bimolecular nucleophilic substitution (S_NAr) reaction in aromatic compounds.

Solution:

S_NAr reactions are accelerated by electron-withdrawing groups, such as the nitro group, because they stabilize the negatively charged Meisenheimer complex (cyclohexadienyl carbanion) intermediate. Therefore, S_NAr reactions occur at the position that allows for this nitro group stabilization of the intermediate.
