The percentage p-character in sp3 hybridisation is _______

Options

A. 25%
B. 50%
C. 75%
D. 66.6%

Answer

To find the percentage of p-character in sp³ hybridization, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Hybridization**:
- In sp³ hybridization, one s orbital and three p orbitals combine to form four equivalent sp³ hybrid orbitals.

2. **Count the Number of Orbitals**:
- The total number of orbitals involved in sp³ hybridization is 4 (1 s orbital + 3 p orbitals).

3. **Determine the Number of p Orbitals**:
- In sp³ hybridization, there are 3 p orbitals.

4. **Calculate the Percentage of p Character**:
- The formula to calculate the percentage of p character is:
\[ \text{Percentage of p character} = \left( \frac{\text{Number of p orbitals}}{\text{Total number of orbitals}} \right) \times 100 \]
- Substituting the values:
\[ \text{Percentage of p character} = \left( \frac{3}{4} \right) \times 100 \]

5. **Perform the Calculation**:
- Calculate \( \frac{3}{4} \) which equals 0.75.
- Now, multiply by 100:
\[ 0.75 \times 100 = 75\% \]

6. **Conclusion**:
- The percentage of p-character in sp³ hybridization is 75%.

### Final Answer:
The percentage p-character in sp³ hybridization is **75%**.
