The shape and hybridisation of some xenon oxyfluorides are given. Choese the wrong set.

Options

A. ` XeOF _ 2 ` - T- shapes ` s p ^ 3 d `
B. ` XeOF_ 4 ` - Square pyramidal ` sp ^ 3 d ^ 2 `
C. `XeO _ 2 F _ 2 ` - Distorted trigonal bipyramidal ` -sp^ 3 d `
D. ` XeO_ 3 F _ 2 ` - Octahedral ` sp^ 3 d `

Explanation

To solve the problem of identifying the wrong set of shape and hybridization for xenon oxyfluorides, we will analyze each compound step by step.

### Step 1: Analyze XeOF2
1. **Structure**: The structure of XeOF2 consists of xenon (Xe) bonded to one oxygen (O) with a double bond and two fluorine (F) atoms.
2. **Lone Pairs**: There are two lone pairs on the xenon atom.
3. **Hybridization**: The hybridization of XeOF2 is sp³d.
4. **Shape**: The molecular geometry is T-shaped due to the presence of the lone pairs.

**Conclusion**: The set for XeOF2 is correct: T-shaped and sp³d.

### Step 2: Analyze XeOF4
1. **Structure**: The structure of XeOF4 consists of xenon (Xe) bonded to four fluorine (F) atoms and one oxygen (O) with double bonds.
2. **Lone Pairs**: There are no lone pairs on the xenon atom.
3. **Hybridization**: The hybridization of XeOF4 is sp³d².
4. **Shape**: The molecular geometry is square pyramidal.

**Conclusion**: The set for XeOF4 is correct: Square pyramidal and sp³d².

### Step 3: Analyze XeO2F2
1. **Structure**: The structure of XeO2F2 consists of xenon (Xe) bonded to two oxygen (O) atoms with double bonds and two fluorine (F) atoms.
2. **Lone Pairs**: There is one lone pair on the xenon atom.
3. **Hybridization**: The hybridization of XeO2F2 is sp³d.
4. **Shape**: The molecular geometry is distorted trigonal bipyramidal.

**Conclusion**: The set for XeO2F2 is correct: Distorted trigonal bipyramidal and sp³d.

### Step 4: Analyze XeO3F2
1. **Structure**: The structure of XeO3F2 consists of xenon (Xe) bonded to three oxygen (O) atoms with double bonds and two fluorine (F) atoms.
2. **Lone Pairs**: There are no lone pairs on the xenon atom.
3. **Hybridization**: The hybridization of XeO3F2 is sp³d.
4. **Shape**: The molecular geometry is trigonal bipyramidal.

**Conclusion**: The set for XeO3F2 is incorrect as it is stated to be octahedral, while it should be trigonal bipyramidal.

### Final Answer
The wrong set is for **XeO3F2**, which is stated to have an octahedral shape instead of the correct trigonal bipyramidal shape.
