An organic halogen compound which is used as refrigerant in refrigerators and air conditioners is

Options

A. BHC
B. `C Cl_4`
C. freon
D. `CHCl_3`

Answer

To solve the question regarding the organic halogen compound used as a refrigerant in refrigerators and air conditioners, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an organic halogen compound that serves as a refrigerant. Refrigerants are substances used in cooling systems, such as refrigerators and air conditioners.

2. **Identifying the Options**: The options provided are:
- A) BHC (Benzene Hexachloride)
- B) CCl4 (Carbon Tetrachloride)
- C) Freon
- D) CSCl3 (Carbon Trisulfide)

3. **Analyzing Each Option**:
- **BHC**: This is primarily used as an insecticide and not as a refrigerant.
- **CCl4**: While Carbon Tetrachloride has been used in the past as a solvent and cleaning agent, it is not commonly used as a refrigerant due to its toxicity and environmental concerns.
- **Freon**: This is a trade name for a group of halocarbon products, primarily used as refrigerants. The most common type is dichlorodifluoromethane (CCl2F2), which is widely used in refrigeration and air conditioning systems.
- **CSCl3**: Carbon Trisulfide is not used as a refrigerant and is more known for its use in organic synthesis.

4. **Selecting the Correct Answer**: Based on the analysis, the only option that is recognized as a refrigerant is **Freon**.

5. **Conclusion**: Therefore, the correct answer to the question is **Freon**.

### Final Answer:
The organic halogen compound which is used as a refrigerant in refrigerators and air conditioners is **Freon**.
