Oxygen does not react with

Options

A. P
B. Na
C. S
D. Cl

Answer

To solve the question "Oxygen does not react with," we will analyze the reactivity of oxygen with various elements.

### Step-by-Step Solution:

1. **Identify the Elements Given**: The question implies we need to check the reactivity of oxygen with several elements, including phosphorus, sodium, sulfur, and chlorine.

2. **Reactivity with Phosphorus**:
- When phosphorus (P) reacts with oxygen (O2), it forms phosphorus pentoxide (P4O10).
- **Conclusion**: Oxygen does react with phosphorus.

3. **Reactivity with Sodium**:
- Sodium (Na) reacts with oxygen to form sodium oxide (Na2O).
- **Conclusion**: Oxygen does react with sodium.

4. **Reactivity with Sulfur**:
- Sulfur (S) reacts with oxygen to produce sulfur dioxide (SO2) or sulfur trioxide (SO3).
- **Conclusion**: Oxygen does react with sulfur.

5. **Reactivity with Chlorine**:
- Chlorine (Cl2) does not react with oxygen under standard conditions. The reaction is endothermic, meaning it requires heat to proceed, which is not favorable under normal conditions.
- **Conclusion**: Oxygen does not react with chlorine.

### Final Answer:
Oxygen does not react with chlorine.
