Which compound is produced when fluorine reacts with water ?

Options

A. `HF and O_3`
B. `HF and O_2`
C. `HF and OF_2`
D. `HF, O_2 and O_3`

Answer

To determine the compound produced when fluorine reacts with water, we can analyze the chemical reactions involved.

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in this reaction are fluorine (F₂) and water (H₂O).

2. **Write the Reaction**: When fluorine reacts with water, the reaction can be represented as:
\[ 2F_2 + 2H_2O \rightarrow 4HF + O_2 \]
This indicates that two molecules of fluorine react with two molecules of water to produce four molecules of hydrofluoric acid (HF) and one molecule of oxygen gas (O₂).

3. **Consider Alternative Reaction**: If we consider a larger quantity of fluorine reacting with water:
\[ 3F_2 + 3H_2O \rightarrow 6HF + O_3 \]
This shows that three molecules of fluorine can also react with three molecules of water to produce six molecules of hydrofluoric acid (HF) and one molecule of ozone (O₃).

4. **Identify the Compounds Produced**: From the reactions above, we can see that the compounds produced when fluorine reacts with water are:
- Hydrofluoric acid (HF)
- Oxygen (O₂)
- Ozone (O₃)

5. **Conclusion**: Therefore, the compounds produced when fluorine reacts with water are HF, O₂, and O₃.

### Final Answer:
The correct answer is that the compounds produced when fluorine reacts with water are HF, O₂, and O₃.
