One of the hydrolysed product of the following compound does not react with silica of glass vessel:

Options

A. `BF_(3)`
B. `ClF_(5)`
C. `XeF_(2)`
D. `SF_(4)`

Explanation

To solve the question regarding which hydrolyzed product does not react with silica of a glass vessel, we will analyze the hydrolysis of each given compound step by step.

### Step-by-Step Solution:

1. **Identify the Compounds**: The compounds provided are HF, ClF5, XeF2, SF4, and BF3.

2. **Analyze Hydrolysis of Each Compound**:
- **HF**: Hydrofluoric acid is known to react with silica (SiO2) to form silicon fluoride (SiF4). Therefore, HF is not the correct answer.

- **ClF5**: When ClF5 is hydrolyzed, it produces HF and HCl. Since HF reacts with silica, this option is also incorrect.

- **XeF2**: Hydrolysis of xenon difluoride (XeF2) yields HF and XeO3. HF reacts with silica, making this option incorrect as well.

- **SF4**: Sulfur tetrafluoride (SF4) hydrolyzes to produce HF and H2SO4. HF reacts with silica, so this option is also incorrect.

- **BF3**: Boron trifluoride (BF3) hydrolyzes to form boric acid (H3BO3) and hydrofluoric acid (HBF4). However, H3BO3 does not react with silica. Therefore, this is the correct answer.

3. **Conclusion**: The hydrolyzed product that does not react with silica is from the hydrolysis of BF3, which produces H3BO3.

### Final Answer:
The correct answer is **BF3**.
