Properties and Reactions of Diazonium Salts
Learn about the preparation, stability, and key reactions of diazonium salts, including Sandmeyer, deamination, and azo coupling reactions.
Why this shows up in the exam
You must predict products and mechanisms involving diazonium salts in both NEET and JEE.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Given below are two statements : Statement I : Benzenediazonium salt is prepared by the reaction of aniline with nitrous acid at 273-278 K. It decomposes easily in the dry state. Statement II : Insertion of iodine into the benzene ring is difficult and hence iodobenzene is prepared through the reaction of benzenediazonium salt with KI. In the light of the above statements, choose the most appropriate answer from the options given below:
