Chlorobenzene on treatment with sodium in dry ether gives diphenyl. The name of the reaction is

Options

A. Fitting reaction
B. Wurtz-Fitting reaction
C. Sandmeyer reaction
D. Gattermann reaction

Explanation

To solve the question regarding the reaction of chlorobenzene with sodium in dry ether to form diphenyl, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactant in this reaction is chlorobenzene (C6H5Cl) and sodium (Na) in dry ether.

2. **Understand the Reaction Type**:
- This reaction involves the coupling of two chlorobenzene molecules. Sodium acts as a reducing agent.

3. **Write the Reaction**:
- The reaction can be represented as:
\[ 2 \text{C}_6\text{H}_5\text{Cl} + 2 \text{Na} \rightarrow \text{C}_{12}\text{H}_{10} + 2 \text{NaCl} \]
- Here, diphenyl (C12H10) is formed along with sodium chloride (NaCl).

4. **Name the Reaction**:
- The reaction is known as the **Wurtz Reaction** or more specifically, the **Wurtz-Fittig Reaction** when it involves aryl halides like chlorobenzene.

5. **Conclusion**:
- Therefore, the name of the reaction where chlorobenzene is treated with sodium in dry ether to produce diphenyl is the **Wurtz Reaction**.

### Final Answer:
The name of the reaction is the **Wurtz Reaction**.
