Conversion of benzene diazonium chloride to chloro benzene is an example of which of the following reactions?

Options

A. Claisen
B. Friedel-craft
C. Sandmeyer
D. Wurtz

Answer

To determine the type of reaction that converts benzene diazonium chloride to chlorobenzene, we can analyze the options provided and identify the correct reaction mechanism.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactant is benzene diazonium chloride (C6H5-N2^+Cl^-).
- The product is chlorobenzene (C6H5-Cl).

2. **Understand the Reaction Mechanism**:
- The conversion of benzene diazonium chloride to chlorobenzene involves the substitution of the diazonium group (N2^+) with a chlorine atom (Cl).
- This reaction typically occurs in the presence of a copper halide (CuX), where X is a halogen (in this case, Cl).

3. **Identify the Type of Reaction**:
- This reaction is known as the **Sandmeyer's Reaction**. In this reaction, the diazonium salt is treated with copper(I) chloride (CuCl), leading to the formation of chlorobenzene and the release of nitrogen gas (N2).

4. **Conclusion**:
- Therefore, the conversion of benzene diazonium chloride to chlorobenzene is an example of the **Sandmeyer's Reaction**.

### Final Answer:
The conversion of benzene diazonium chloride to chlorobenzene is an example of **Sandmeyer's Reaction**.
