The chlorination of methane to give `C Cl_(4)` is an example of -

Options

A. An addition reaction
B. An elimination reaction
C. A reduction reaction
D. A substitution reaction

Answer

To determine the type of reaction that occurs during the chlorination of methane to produce carbon tetrachloride (CCl₄), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactant is methane (CH₄).
- The product is carbon tetrachloride (CCl₄).

2. **Understand the Reaction Process**:
- In the chlorination of methane, each hydrogen atom in methane is replaced by a chlorine atom. This means that the four hydrogen atoms in CH₄ are substituted by four chlorine atoms.

3. **Determine the Type of Reaction**:
- The process where one atom or group of atoms is replaced by another atom or group of atoms is called a **substitution reaction**.
- In this case, the hydrogen atoms are substituted by chlorine atoms.

4. **Conclusion**:
- Therefore, the chlorination of methane to produce CCl₄ is an example of a **substitution reaction**.

### Final Answer:
The chlorination of methane to give CCl₄ is an example of a **substitution reaction**.
