Question

p-Iodonitrobenzene can be synthesized from p-nitroaniline.

(a) True

(b) False

This question was addressed to me in an international level competition.

My question is based upon Diazonium Salts in Synthesis of Aromatic Compounds in portion Amines of Chemistry – Class 12

Answer 1

Correct choice is (a) True

To explain I would say: p-Nitroaniline on diazotisation gives p-nitrobenzenediazonium chloride with on treatment with potassium iodide replaces the N2^+Cl^– group to give p-iodonitrobenzene.
