Answer

To solve the question of identifying the incorrect statement regarding borazole (B3N3H6), we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Borazole Structure**:
- Borazole, also known as borazine, has the formula B3N3H6.
- Its structure resembles that of benzene, consisting of alternating boron (B) and nitrogen (N) atoms.

2. **Analyzing Hybridization of Nitrogen in Borazole**:
- In borazole, the nitrogen atoms are sp² hybridized because they form three sigma bonds (two with boron and one with hydrogen) and have one lone pair.
- The p-character in sp² hybridization is calculated as follows:
\[ \text{p-character} = \frac{\text{number of p orbitals}}{\text{total number of orbitals}} \times 100 = \frac{2}{3} \times 100 = 66.67\% \]

3. **Comparing with Ammonia (NH3)**:
- In ammonia (NH3), nitrogen is sp³ hybridized, forming three sigma bonds with hydrogen and having one lone pair.
- The p-character in sp³ hybridization is:
\[ \text{p-character} = \frac{1}{4} \times 100 = 25\% \]
- Thus, the p-character of nitrogen in borazole (66.67%) is indeed greater than that in ammonia (25%).

4. **Evaluating the Statements**:
- **Option 1**: The p-character in the hybrid orbital of nitrogen in borazole is more than that in ammonia. This statement is **correct**.
- **Option 2**: Borazole exhibits resonance. This statement is **correct** as borazole has alternating double bonds.
- **Option 3**: The Lewis acid character in borazole is less than that in Bi3. This statement is **correct** because Bi3 has a stronger Lewis acid character due to the larger size of bismuth compared to boron.
- **Option 4**: Borazole has a conjugated structure resulting from an intermolecular acid-base reaction. This statement is **correct**.

5. **Conclusion**:
- Since all options except for Option 1 are correct, the incorrect statement is **Option 1**.

### Final Answer:
The incorrect statement is **Option 1**.
