What part of the CFC molecule attacks ozone?

Options

A. The hydrogen
B. The fluorine
C. The chlorine
D. The carbon

Answer

### Step-by-Step Solution:

1. **Understanding CFCs**: CFC stands for Chlorofluorocarbon, which is a chemical compound known to deplete the ozone layer in the stratosphere.

2. **Reaction with Ozone**: When CFCs are released into the atmosphere, they eventually reach the stratosphere where they react with ozone (O3).

3. **Identifying the Reactive Part**: The specific part of the CFC molecule that interacts with ozone is the chlorine atom. In the case of the example given (CFCl2), it is the chlorine (Cl) that is responsible for the reaction.

4. **Chemical Reaction**: When chlorine from CFCs reacts with ozone, it forms chlorine monoxide (ClO) and oxygen (O2). This reaction is harmful as it leads to the depletion of the ozone layer.

5. **Conclusion**: Therefore, the part of the CFC molecule that attacks ozone is the chlorine atom.

### Final Answer:
The part of the CFC molecule that attacks ozone is the chlorine atom.
