The above reaction is known as :

Options

A. Finkelstein reaction
B. Stephen's reaction
C. Kolbe's reaction
D. Wurtz reaction

Answer

To determine the name of the reaction given by the equation:

\[ (CH_3)_2CHCl + NaI \overset{\text{Acetone}}{\rightarrow} (CH_3)_2CHI + NaCl \]

we will analyze the components and the process involved step by step.

### Step 1: Identify the Reactants and Products
The reactants in the equation are:
- \( (CH_3)_2CHCl \) (which is 2-chloro-2-methylpropane)
- \( NaI \) (sodium iodide)

The products are:
- \( (CH_3)_2CHI \) (which is 2-iodo-2-methylpropane)
- \( NaCl \) (sodium chloride)

### Step 2: Understand the Reaction Type
This reaction involves the substitution of a chlorine atom (Cl) in the alkyl halide \( (CH_3)_2CHCl \) with an iodine atom (I) from sodium iodide \( NaI \). This type of reaction is characterized by the exchange of halogens.

### Step 3: Role of Solvent
The reaction takes place in the presence of acetone, which acts as a solvent. Acetone is a polar aprotic solvent that helps to solubilize \( NaI \) and facilitates the reaction by stabilizing the ions formed during the halogen exchange.

### Step 4: Naming the Reaction
The specific type of halogen exchange reaction occurring here is known as the **Finkelstein reaction**. This reaction is named after the chemist who first described it and is commonly used to convert alkyl chlorides to alkyl iodides.

### Conclusion
Thus, the reaction given in the question is known as the **Finkelstein reaction**.
