Name the gas obtained during the processing of coal to get coke :

Options

A. Coke
B. Coal tar
C. Coal gas
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Process**: The question asks about the gas produced during the processing of coal to obtain coke. The process involves heating coal in the absence of air (oxygen).

2. **Heating Coal**: When coal is heated without air, it undergoes a process called carbonization. This process breaks down the coal and results in several by-products.

3. **By-Products of Carbonization**: During the carbonization of coal, several products are formed:
- **Coke**: This is the solid black residue that remains after the process.
- **Coal Tar**: This is a thick, black liquid that contains various organic compounds.
- **Coal Gas**: This is the gaseous product that is formed during the process.

4. **Identifying the Gas**: The question specifically asks for the gas obtained. The main gas produced during the carbonization of coal is known as **coal gas**.

5. **Composition of Coal Gas**: Coal gas primarily consists of:
- Methane (CH₄)
- Hydrogen (H₂)
- A small amount of Carbon Dioxide (CO₂)

6. **Final Answer**: Therefore, the gas obtained during the processing of coal to get coke is **coal gas**.
