Question

What happens when benzonium chloride is treated with ki?

Answer 1

Nitrogen Gas Is Released & IodoBenzene Product Is Formed

Answer 2

The nitrogen is released as nitrogen gas. To get this reaction, all you need to do is warm the benzenediazonium chloride[C6H5N2]Cl solution. The diazonium ion reacts with the water in the solution and phenol C6H5OH is formed - either in solution or as a black oily liquid (depending on how much is formed). Nitrogen gas is evolved. The reaction is following,

C6H5ClN2 + H2O ———> C6H5OH + HCl + N2

This reaction results the formation of phenol C6H5OH with evolution of Nitrogen gas N2 and Hydrochloric Acid HCl.
