What is used as a medium in Wurtz reaction ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Wurtz Reaction**: The Wurtz reaction involves the coupling of alkyl halides (R-X, where X is a halogen like Cl, Br, or I) with sodium metal (Na) to form higher alkanes (R-R) and sodium halide (NaX).

2. **Identifying the Medium**: In the Wurtz reaction, a suitable solvent is required to facilitate the reaction. The solvent must be able to dissolve both the alkyl halide and sodium metal without reacting with them.

3. **Choosing the Right Solvent**: The solvent used in the Wurtz reaction is **dry ether**. Dry ether is chosen because it is an anhydrous solvent that does not contain water. Water would react with sodium metal, which would interfere with the desired reaction.
