A sp3 hybrid orbital contains: what percent of S character

Explanation

To determine the percentage of S character in an sp³ hybrid orbital, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Hybridization**:
- The question specifies that we are dealing with sp³ hybridization.

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

3. **Count the Total Orbitals**:
- Total orbitals involved in sp³ hybridization = 1 (from s) + 3 (from p) = 4 orbitals.

4. **Calculate the S Character**:
- The S character is determined by the ratio of the number of s orbitals to the total number of orbitals.
- Since there is 1 s orbital in sp³ hybridization, the S character can be calculated as follows:
\[ \text{S character} = \frac{\text{Number of s orbitals}}{\text{Total number of orbitals}} = \frac{1}{4} \]

5. **Convert to Percentage**:
- To express this as a percentage, multiply by 100:
\[ \text{Percentage of S character} = \frac{1}{4} \times 100 = 25\% \]

6. **Conclusion**:
- Therefore, an sp³ hybrid orbital contains **25% S character**.
