Options

A. Wurtz reaction
B. Fitting reaction
C. Wurtz-Fitting reaction
D. Finkelstein's reaction .

Answer

To determine the name of the reaction represented by the equation \( RCl + NaI \overset{\text{Dry acetone}}{\rightarrow} R-I + NaCl \), we can analyze the components and the type of reaction taking place.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactants are \( RCl \) (an alkyl chloride) and \( NaI \) (sodium iodide).
- The products are \( R-I \) (an alkyl iodide) and \( NaCl \) (sodium chloride).

2. **Understand the Reaction Conditions**:
- The reaction occurs in the presence of dry acetone, which is a polar aprotic solvent. This solvent helps facilitate the nucleophilic substitution reaction.

3. **Recognize the Type of Reaction**:
- The reaction involves the substitution of the chlorine atom in \( RCl \) with an iodine atom from \( NaI \). This is characteristic of a nucleophilic substitution reaction.

4. **Name the Reaction**:
- This specific type of nucleophilic substitution, where an alkyl halide is converted to another alkyl halide (in this case, from chloride to iodide), is known as the **Finkelstein reaction**.

5. **Conclusion**:
- Therefore, the reaction \( RCl + NaI \overset{\text{Dry acetone}}{\rightarrow} R-I + NaCl \) is known as the **Finkelstein reaction**.
