Which of the following hybridisation has maximum s-characters

Options

A. `sp^(3)`
B. `sp^(2)`
C. `sp`
D. none of these

Explanation

To determine which hybridization has the maximum s-character, we will analyze the s-character of different types of hybridization: sp, sp², and sp³.

### Step-by-Step Solution:

1. **Understand Hybridization Types**:
- Hybridization can be of different types: sp, sp², and sp³.
- Each type has a different number of s and p orbitals involved.

2. **Calculate s-character for sp Hybridization**:
- In sp hybridization, there is **1 s orbital** and **1 p orbital** involved.
- Total orbitals = 1 (s) + 1 (p) = 2.
- Percentage s-character = (Number of s orbitals / Total number of orbitals) × 100
- Percentage s-character for sp = (1 / 2) × 100 = **50%**.

3. **Calculate s-character for sp² Hybridization**:
- In sp² hybridization, there is **1 s orbital** and **2 p orbitals** involved.
- Total orbitals = 1 (s) + 2 (p) = 3.
- Percentage s-character = (1 / 3) × 100 = **33.3%**.

4. **Calculate s-character for sp³ Hybridization**:
- In sp³ hybridization, there is **1 s orbital** and **3 p orbitals** involved.
- Total orbitals = 1 (s) + 3 (p) = 4.
- Percentage s-character = (1 / 4) × 100 = **25%**.

5. **Compare the s-characters**:
- sp: 50%
- sp²: 33.3%
- sp³: 25%
- The hybridization with the maximum s-character is **sp hybridization** with **50% s-character**.

### Conclusion:
The hybridization with the maximum s-character is **sp hybridization**.
