Match the items of column 1 and column 2 and mark the correct option.
`{:(,"Column 1",,"Column 2"),((A),"Its partial hydrolysis does not change oxidation state of central atom",(1),He),((B),"It is used in modern diving apparatus",(2),XeF_(6)),((C),"It is used to provide inert atmosphere for filling electrical bulbs",(3),XeF_(4)),((D),"Its central atom is in "sp^(3)d^(2)" hybridisation",(4),Ar):}`

Options

A. A–1, B–4, C–2, D–3
B. A–1, B–2, C–3, D–4
C. A–2, B–1, C–4, D–3
D. A–1, B–3, C–2, D–4

Answer

To solve the problem of matching the items from Column 1 with Column 2, we will analyze each statement in Column 1 and find the corresponding item in Column 2.

### Step-by-Step Solution:

1. **Analyze Statement A**: "Its partial hydrolysis does not change oxidation state of central atom."
- The only compound that fits this description is **XeF₆**. When XeF₆ undergoes partial hydrolysis, it forms XeF₄ and does not change the oxidation state of xenon (remains +6).
- **Match**: A → (2) XeF₆

2. **Analyze Statement B**: "It is used in modern diving apparatus."
- Helium is commonly used in diving apparatus due to its low solubility in body tissues and non-toxicity at high pressures.
- **Match**: B → (1) He

3. **Analyze Statement C**: "It is used to provide inert atmosphere for filling electrical bulbs."
- Argon is an inert gas that is widely used to fill electrical bulbs to prevent the filament from oxidizing.
- **Match**: C → (4) Ar

4. **Analyze Statement D**: "Its central atom is in 'sp³d²' hybridization."
- The compound **XeF₄** has a central xenon atom that undergoes sp³d² hybridization, as it has four bonding pairs and two lone pairs.
- **Match**: D → (3) XeF₄

### Final Matches:
- A → (2) XeF₆
- B → (1) He
- C → (4) Ar
- D → (3) XeF₄

### Conclusion:
The correct option based on the matches is **Option 3**.
