Which of the following statement is incorrect regarding `B_(2)H_(6)` ?

Options

A. Each boron atom is `sp^(3)` hybridised
B. `B_(2) H_(6)` is electron deficient
C. `B_(2) H_(6)` has banana bond
D. All of these

Answer

To determine which statement is incorrect regarding \( B_2H_6 \) (diborane), we will analyze the properties and characteristics of the molecule based on the information provided.

### Step-by-Step Solution:

1. **Understanding the Structure of Diborane (\( B_2H_6 \))**:
- Diborane consists of two boron atoms and six hydrogen atoms.
- The structure features two types of bonds: terminal \( B-H \) bonds and bridging \( B-H-B \) bonds.
- The bridging bonds are three-center two-electron bonds, often referred to as "banana bonds" due to their shape.

2. **Hybridization**:
- Each boron atom in diborane is sp³ hybridized.
- This is because each boron atom forms four bonds: two terminal \( B-H \) bonds and two bridging \( B-H-B \) bonds.

3. **Electron Deficiency**:
- Diborane is known to be an electron-deficient molecule.
- Each boron atom contributes three valence electrons, and the total number of electrons in the molecule is 12 (from 6 hydrogen atoms and 2 boron atoms).
- However, due to the nature of the bonding, each boron atom effectively has only 6 electrons around it, which does not satisfy the octet rule.

4. **Identifying the Statements**:
- **Statement 1**: "Each boron atom is sp³ hybridized." - This statement is correct.
- **Statement 2**: "B2H6 is an electron-deficient molecule." - This statement is correct.
- **Statement 3**: "B2H6 has banana bonds." - This statement is also correct.

5. **Conclusion**:
- Since all the statements provided about \( B_2H_6 \) are correct, the answer to the question "Which of the following statement is incorrect regarding \( B_2H_6 \)?" is that there is no incorrect statement among the options provided.

### Final Answer:
All statements regarding \( B_2H_6 \) are correct.
