If the central atom is of third row or below this in the periodic table, then lone pair will occupy a stereochemically inactive s-orbital and bonding will be through almost pure p-orbitals and bond angles are nearly `90^(@)`, if the substituent's electronegativity value is `le 2.5`.
The hybridisation of atomic orbitals of central atom "Xe" in `XeO_(4), XeO_(2)F_(2) and XeOF_(4)` respectively.

Options

A. `sp^(3),sp^(3)d^(2),sp^(3)d^(2)`
B. `sp^(3)d,sp^(3)d,sp^(3)d^(2)`
C. `sp^(3),sp^(3)d^(2),sp^(3)d`
D. `sp^(3),sp^(3)d,sp^(3)d^(2)`

Answer

To determine the hybridization of the central atom xenon (Xe) in the compounds XeO4, XeO2F2, and XeOF4, we will follow these steps:

### Step 1: Determine the Valence Electrons of Xenon
Xenon is in Group 18 of the periodic table and has 8 valence electrons.

### Step 2: Analyze the Compounds
1. **XeO4**:
- Each oxygen (O) atom forms 2 bonds (1 sigma and 1 pi).
- There are 4 oxygen atoms, contributing to 4 bonding pairs.
- Since there are no lone pairs on xenon in this compound, the total number of electron pairs is 4 (bonding pairs).
- **Hybridization**: The hybridization is sp³ (4 electron pairs).

2. **XeO2F2**:
- Each oxygen atom forms 2 bonds (1 sigma and 1 pi), contributing 2 bonding pairs.
- Each fluorine (F) atom forms 1 bond, contributing 2 more bonding pairs.
- This gives a total of 4 bonding pairs.
- Xenon has 1 lone pair remaining after forming these bonds.
- **Total Electron Pairs**: 4 bonding pairs + 1 lone pair = 5.
- **Hybridization**: The hybridization is sp³d.

3. **XeOF4**:
- Each oxygen atom forms 2 bonds (1 sigma and 1 pi), contributing 2 bonding pairs.
- Each fluorine atom forms 1 bond, contributing 4 more bonding pairs.
- This gives a total of 4 bonding pairs from the fluorine and 1 from oxygen.
- There is 1 lone pair remaining on xenon.
- **Total Electron Pairs**: 4 bonding pairs + 1 lone pair = 5.
- **Hybridization**: The hybridization is sp³d².

### Summary of Hybridization
- **XeO4**: sp³
- **XeO2F2**: sp³d
- **XeOF4**: sp³d²

### Final Answer
- The hybridization of Xe in XeO4 is sp³.
- The hybridization of Xe in XeO2F2 is sp³d.
- The hybridization of Xe in XeOF4 is sp³d².
