Question

Given below are two statements:
Statement I: Benzenediazonium chloride is a colourless crystalline solid. It is insoluble in water but reacts with water when warmed.
Statement II: Benzenediazonium chloride on reacting with $HCl$ in presence of copper powder gives chlorobenzene as the product. This is an example of Gatterman reaction.
In the light of the above statements, choose the correct answer from the options given below:

Accepted Answer

**Statement I is false:** Benzenediazonium chloride is a colourless crystalline solid that is **readily soluble** in water, not insoluble. It is stable in cold water but reacts with water when warmed to form phenol.

**Statement II is true:** The conversion of benzenediazonium chloride to chlorobenzene or bromobenzene by treating it with $HCl$ or $HBr$ in the presence of finely divided **copper powder** is known as the **Gatterman reaction**.
