Quizplus · Accepted Answer

The reaction of 1-chloro-2,4-dinitrobenzene with sodium hydroxide to give 2,4-dinitrophenol involves the formation of a Meisenheimer complex, which is a type of intermediate formed in nucleophilic aromatic substitution reactions, especially when dealing with electron-withdrawing groups like nitro groups on the benzene ring.
