Incorrect among the following

Options

A. `(BN)_(x)` is molecule with sp sate of hybridisation
B. `(BN)_(x)` is a molecule with graphite like structure
C. `(BN)_(x)` is a molecule with `sp^(2)` hybridisation
D. `BN ` is prepared by reaction of `B_(2)O_(3)` and `NH_(3)`

Answer

To determine the incorrect statement among the given options regarding boron nitride (BN), we will analyze each statement step by step.

### Step 1: Analyze Statement A
**Statement A:** "BN is a molecule with sp hybridization."

- **Analysis:** Boron nitride (BN) can exist in different forms, one of which is hexagonal boron nitride (h-BN). In this structure, each boron atom is bonded to three nitrogen atoms in a planar arrangement, leading to sp² hybridization. Therefore, the statement claiming sp hybridization is incorrect.

### Step 2: Analyze Statement B
**Statement B:** "BN has a graphite-like structure."

- **Analysis:** Hexagonal boron nitride indeed has a structure similar to that of graphite, consisting of layers of hexagonal arrangements of boron and nitrogen atoms. This statement is correct.

### Step 3: Analyze Statement C
**Statement C:** "BN is a molecule having sp² hybridization."

- **Analysis:** As previously mentioned, in hexagonal boron nitride, the boron atoms are sp² hybridized. This statement is correct.

### Step 4: Analyze Statement D
**Statement D:** "BN is prepared by the reaction of B₂O₃ with ammonia."

- **Analysis:** Boron nitride can be synthesized from boron oxide (B₂O₃) and ammonia (NH₃), resulting in the formation of boron nitride and water. This statement is also correct.

### Conclusion
After analyzing all the statements, we find that:
- **Statement A** is incorrect because boron nitride has sp² hybridization, not sp hybridization.

Thus, the answer to the question is **Statement A**.
