Answer

To analyze the reaction \( \text{BF}_3 + \text{H}_2\text{O} \rightarrow \text{H}_3\text{BO}_3 + \text{H[BF}_4] \) and determine the nature of the products, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactants are \( \text{BF}_3 \) (Boron Trifluoride) and \( \text{H}_2\text{O} \) (Water).
- The products are \( \text{H}_3\text{BO}_3 \) (Boric Acid) and \( \text{H[BF}_4] \) (Hydrofluoroborate Ion).

2. **Determine the Nature of the Products**:
- We need to check if \( \text{H}_3\text{BO}_3 \) is an oxyacid.
- An oxyacid must contain:
- At least one hydrogen atom.
- At least one oxygen atom.
- At least one other element (in this case, Boron).

3. **Check the Structure of \( \text{H}_3\text{BO}_3 \)**:
- The molecular structure of \( \text{H}_3\text{BO}_3 \) can be represented as:
\[ \text{B(OH)}_3 \]
- This indicates that it has three hydroxyl (–OH) groups.

4. **Verify the Oxyacid Conditions**:
- **Condition 1**: Contains hydrogen - Yes, it has three hydrogen atoms.
- **Condition 2**: Contains oxygen - Yes, it has three oxygen atoms.
- **Condition 3**: Contains another element - Yes, it has Boron.
- **Condition 4**: At least one hydrogen must be bonded to oxygen and can dissociate to form \( \text{H}^+ \) - Yes, the hydrogen in the hydroxyl groups can dissociate.

5. **Conclusion about the Product**:
- Since \( \text{H}_3\text{BO}_3 \) meets all the criteria for being an oxyacid, we can conclude that it is indeed an oxyacid.
- Furthermore, the suffix of the acid is "IC", which is characteristic of oxyacids derived from non-metals.

6. **Select the Correct Option**:
- Based on the analysis, the correct option is:
- **Option A**: If the product is an oxyacid with a suffix.
