Which of the following compounds have same hybridisation?

Options

A. `ClF_(3)`
B. `PF_(5)`
C. `XeF_(4)`
D. `SF_(4)`

Answer

To determine which compounds have the same hybridization, we will calculate the hybridization for each compound using the formula for steric number. The formula for hybridization is:

\[ \text{Hybridization} = \frac{1}{2} \left( \text{Number of valence electrons of central atom} + \text{Number of monovalent atoms attached} + \text{Charge} \right) \]

Let's analyze each compound step by step.

### Step 1: Calculate Hybridization of ClF3
- **Central Atom**: Chlorine (Cl)
- **Valence Electrons of Cl**: 7
- **Monovalent Atoms Attached**: 3 (Fluorine atoms)
- **Charge**: 0 (no charge)

Using the formula:
\[ \text{Hybridization} = \frac{1}{2} (7 + 3 + 0) = \frac{10}{2} = 5 \]
- **Steric Number**: 5
- **Hybridization**: sp³d

### Step 2: Calculate Hybridization of PF5
- **Central Atom**: Phosphorus (P)
- **Valence Electrons of P**: 5
- **Monovalent Atoms Attached**: 5 (Fluorine atoms)
- **Charge**: 0 (no charge)

Using the formula:
\[ \text{Hybridization} = \frac{1}{2} (5 + 5 + 0) = \frac{10}{2} = 5 \]
- **Steric Number**: 5
- **Hybridization**: sp³d

### Step 3: Calculate Hybridization of XeF4
- **Central Atom**: Xenon (Xe)
- **Valence Electrons of Xe**: 8
- **Monovalent Atoms Attached**: 4 (Fluorine atoms)
- **Charge**: 0 (no charge)

Using the formula:
\[ \text{Hybridization} = \frac{1}{2} (8 + 4 + 0) = \frac{12}{2} = 6 \]
- **Steric Number**: 6
- **Hybridization**: sp³d²

### Step 4: Calculate Hybridization of SF4
- **Central Atom**: Sulfur (S)
- **Valence Electrons of S**: 6
- **Monovalent Atoms Attached**: 4 (Fluorine atoms)
- **Charge**: 0 (no charge)

Using the formula:
\[ \text{Hybridization} = \frac{1}{2} (6 + 4 + 0) = \frac{10}{2} = 5 \]
- **Steric Number**: 5
- **Hybridization**: sp³d

### Conclusion
From the calculations:
- ClF3: sp³d
- PF5: sp³d
- XeF4: sp³d²
- SF4: sp³d

The compounds that have the same hybridization are **ClF3, PF5, and SF4**, all of which have sp³d hybridization.
