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 which compound is produced when fluorine reacts with water, we need to analyze the chemical reaction that occurs between these two substances.

### Step-by-Step Solution:

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

2. **Write the Balanced Chemical Equation**:
- When fluorine reacts with water, it can produce hydrofluoric acid (HF) and oxygen (O₂). The balanced equation for the reaction is:
\[ 2 \text{F}_2 + 2 \text{H}_2\text{O} \rightarrow 4 \text{HF} + \text{O}_2 \]
- Alternatively, under certain conditions, fluorine can also produce ozone (O₃) along with HF. The reaction can be represented as:
\[ 3 \text{F}_2 + 3 \text{H}_2\text{O} \rightarrow 6 \text{HF} + \text{O}_3 \]

3. **Identify the Products**: From the balanced equations, we can see that the products of the reaction include:
- Hydrofluoric acid (HF)
- Oxygen (O₂)
- Ozone (O₃)

4. **Conclusion**: The main compound produced when fluorine reacts with water is hydrofluoric acid (HF). However, depending on the conditions of the reaction, ozone (O₃) can also be produced.

### Final Answer:
The compounds produced when fluorine reacts with water are hydrofluoric acid (HF) and, under certain conditions, ozone (O₃).
