C. `{:(Column I, Column II),(Cl_(2),r."Reacts with glass"):}`
D. `{:(Column I, Column II),(VCl_(5),s"Polymerisation"),(,t.O_(2) "formation"):}`

Answer

To solve the problem of matching the compounds from Column I with their respective reactions and observations in Column II, we will analyze each compound's reaction with water step by step.

### Step-by-Step Solution:

1. **Identify the Compounds in Column I:**
- The compounds mentioned are:
- \( \text{XF}_4 \)
- \( \text{F}_2 \)
- \( \text{PCl}_5 \)
- \( \text{VCl}_5 \)

2. **Analyze the Reaction of Each Compound with Water:**

- **For \( \text{XF}_4 \):**
- When \( \text{XF}_4 \) is hydrolyzed, it produces \( \text{XO}_3 \), \( \text{XO}_2 \), and \( \text{HCl} \).
- The reaction can be summarized as:
\[ \text{XF}_4 + \text{H}_2\text{O} \rightarrow \text{XO}_3 + \text{XO}_2 + \text{HCl} \]
- **Observation:** Hydrogen halide formation occurs, and there is a possibility of disproportionation.

- **For \( \text{F}_2 \):**
- Hydrolysis of \( \text{F}_2 \) yields \( \text{HF} \) and \( \text{O}_2 \).
- The balanced reaction is:
\[ 2\text{F}_2 + 2\text{H}_2\text{O} \rightarrow 4\text{HF} + \text{O}_2 \]
- **Observation:** Hydrogen halide formation occurs, and HF can dissolve glass.

- **For \( \text{PCl}_5 \):**
- Hydrolysis of \( \text{PCl}_5 \) produces \( \text{H}_3\text{PO}_4 \) and \( \text{HCl} \).
- The reaction can be written as:
\[ \text{PCl}_5 + 4\text{H}_2\text{O} \rightarrow \text{H}_3\text{PO}_4 + 5\text{HCl} \]
- **Observation:** Hydrogen halide formation occurs, but glass does not dissolve.

- **For \( \text{VCl}_5 \):**
- Hydrolysis of \( \text{VCl}_5 \) yields \( \text{VOCl}_3 \) and \( \text{HCl} \).
- The reaction is:
\[ \text{VCl}_5 + 3\text{H}_2\text{O} \rightarrow \text{VOCl}_3 + 5\text{HCl} \]
- **Observation:** Hydrogen halide formation occurs, and glass does not dissolve.

3. **Match the Results with Column II:**
- Based on the observations from the reactions:
- \( \text{XF}_4 \) matches with observation related to hydrogen halide formation and disproportionation.
- \( \text{F}_2 \) matches with observation related to hydrogen halide formation and glass dissolving.
- \( \text{PCl}_5 \) matches with observation related to hydrogen halide formation without glass dissolving.
- \( \text{VCl}_5 \) matches with observation related to hydrogen halide formation without glass dissolving.

### Final Matches:
- \( \text{XF}_4 \) → Observation related to disproportionation and hydrogen halide formation.
- \( \text{F}_2 \) → Observation related to glass dissolving and hydrogen halide formation.
- \( \text{PCl}_5 \) → Observation related to hydrogen halide formation (no glass dissolving).
- \( \text{VCl}_5 \) → Observation related to hydrogen halide formation (no glass dissolving).
