To solve the matching question, we need to determine the hybridization of each compound in Column I and then match them with the appropriate descriptions in Column II. Let's break it down step by step.
### Step 1: Determine the Hybridization of Each Compound
**(A) XeO₃, XeF₂, ClF₃, PCl₅**
1. **XeO₃**:
- Xenon has 8 valence electrons.
- In XeO₃, there are 3 double bonds with oxygen and 1 lone pair left.
- Hybridization: 3 (bond pairs) + 1 (lone pair) = 4 → **sp³**.
2. **XeF₂**:
- Xenon has 8 valence electrons.
- In XeF₂, there are 2 bonds with fluorine and 3 lone pairs left.
- Hybridization: 2 (bond pairs) + 3 (lone pairs) = 5 → **sp³d**.
3. **ClF₃**:
- Chlorine has 7 valence electrons.
- In ClF₃, there are 3 bonds with fluorine and 2 lone pairs left.
- Hybridization: 3 (bond pairs) + 2 (lone pairs) = 5 → **sp³d**.
4. **PCl₅**:
- Phosphorus has 5 valence electrons.
- In PCl₅, there are 5 bonds with chlorine and no lone pairs.
- Hybridization: 5 (bond pairs) = 5 → **sp³d**.
**Summary for (A)**:
- XeO₃: sp³
- XeF₂: sp³d
- ClF₃: sp³d
- PCl₅: sp³d
**Match**: All are sp³d except one (XeO₃). → **(A) → (p)**
