Question

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:

Professor PC Thomas Classes · Answer

(c) : Benzenediazonium chloride is prepared by the reaction of aniline with nitrous acid at $273-278 \mathrm{~K}$. It decomposes easily in the dry state. So, statement I is correct. Iodine is not easily introduced into the benzene ring directly thus, iodobenzene is prepared by treatment of benzene diazonium salt with KI. Hence, statement II is also correct.
