Substitute of chlorofluorocarbon is

Options

A. Hydrofluorofluorocarbons
B. Hydrochlorofluorocarbon
C. Fluorocarbon
D. Both A and B

Answer

**Step-by-Step Solution:**

1. **Understanding Chlorofluorocarbons (CFCs)**:
- CFCs are compounds that contain chlorine, fluorine, and carbon. They are known to contribute to ozone layer depletion.

2. **Identifying Substitutes for CFCs**:
- To address environmental concerns, it is important to find alternatives to CFCs. The two main substitutes are Hydrochlorofluorocarbons (HCFCs) and Hydrofluorocarbons (HFCs).

3. **Defining HCFCs and HFCs**:
- HCFCs (Hydrochlorofluorocarbons) contain hydrogen, chlorine, fluorine, and carbon. They have a lower ozone depletion potential compared to CFCs.
- HFCs (Hydrofluorocarbons) consist of hydrogen, fluorine, and carbon, and do not contain chlorine, making them ozone-friendly.

4. **Evaluating the Options**:
- The question provides options:
- A) Hydrofluorocarbons (HFCs)
- B) Hydrochlorofluorocarbons (HCFCs)
- C) Fluorocarbons
- D) Both A and B
- Since both HCFCs and HFCs are valid substitutes for CFCs, the correct answer is D) Both A and B.

5. **Conclusion**:
- The substitutes for chlorofluorocarbons are Hydrofluorocarbons (HFCs) and Hydrochlorofluorocarbons (HCFCs). Therefore, the answer is both A and B.
