`RX + 2Na + RX overset("Dry ether")to R-R + 2NaX` is called :

Options

A. Sandmeyer's reaction
B. Fittig reaction
C. Wurtz reaction
D. Williamson's synthesis.

Answer

To solve the question regarding the reaction \( RX + 2Na \overset{\text{Dry ether}}{\rightarrow} R-R + 2NaX \), we need to identify the name of this reaction.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in the given reaction are \( RX \) (an alkyl halide) and \( Na \) (sodium metal).

2. **Understand the Reaction Conditions**:
- The reaction takes place in the presence of dry ether, which is a common solvent used in organic reactions.

3. **Analyze the Products**:
- The products of the reaction are \( R-R \) (a new carbon-carbon bond formed between two alkyl groups) and \( 2NaX \) (where \( X \) is a halogen).

4. **Recognize the Type of Reaction**:
- This reaction is a coupling reaction where two alkyl halides are coupled to form a new alkane. It is specifically a reaction that involves the formation of a new carbon-carbon bond.

5. **Name the Reaction**:
- The reaction described is known as the **Wurtz Reaction**. It is characterized by the coupling of alkyl halides using sodium in dry ether.

6. **Choose the Correct Option**:
- Based on the analysis, the correct answer to the question is that this reaction is called the **Wurtz Reaction**.

### Final Answer:
The reaction \( RX + 2Na \overset{\text{Dry ether}}{\rightarrow} R-R + 2NaX \) is called the **Wurtz Reaction**.
