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 HClHCl 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:

A

Both Statement I and Statement II are true.

B

Both Statement I and Statement II are false.

C

Statement I is true but Statement II is false.

D

Statement I is false but Statement II is true.

Step-by-Step Solution

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 HClHCl or HBrHBr in the presence of finely divided copper powder is known as the Gatterman reaction.

Exam Context & Concepts Covered
