Which of the following statement is incorrect?

Options

A. X is ionic in nature
B. Hybridisation state of B in both cationic and anionic part of X is
same.
C. Y has planar structure.
D. Y is covalent and hybridisation state of all B is different.

Explanation

To solve the question regarding the reaction of diborane (B₂H₆) with ammonia (NH₃) and the subsequent products formed, we will analyze the reaction step by step.

### Step 1: Identify the Reactants
The reactants in this reaction are diborane (B₂H₆) and ammonia (NH₃).

### Step 2: Reaction Conditions
The reaction occurs under slow heating. This indicates that the reaction is taking place at a low temperature initially.

### Step 3: Formation of Intermediate Product (X)
When B₂H₆ reacts with NH₃ under slow heating, it forms an intermediate product. The expected product is:
- **X = BH₂NH₃ (twice) + BH₄⁻**

This indicates that we have a cationic part (BH₂NH₃) and an anionic part (BH₄⁻).

### Step 4: Further Heating of Product X
Upon further heating (at a higher temperature), the intermediate product X decomposes to form:
- **Y = B₃N₃H₆**

This compound is also known as borazine, which has a structure similar to benzene.

### Step 5: Analyze the Statements
Now we need to evaluate the statements provided in the question to identify the incorrect one.

1. **Statement 1**: "X is ionic in nature."
- This is **correct** because X consists of a cation (BH₂NH₃) and an anion (BH₄⁻).

2. **Statement 2**: "The hybridization state of both B in both cationic and anionic part of X is the same."
- This is **correct** as both boron atoms in BH₂NH₃ and BH₄⁻ are sp³ hybridized.

3. **Statement 3**: "Y is a planar structure."
- This is **correct** because borazine (Y) has a planar structure similar to benzene.

4. **Statement 4**: "Y is covalent and the hybridization state of all B is different."
- This is **incorrect** because all boron atoms in borazine (Y) have the same hybridization state, which is sp³.

### Conclusion
The incorrect statement among the options provided is:
- **"Y is covalent and the hybridization state of all B is different."**
