The incorrect statement regarding chloral hydrate `C Cl_(3)CH(OH)_(2)` is :-

Options

A. It exhibits intramolecular hydrogen bonding
B. It has 9 lone pair and 9 bond pair
C. It is stable inspite of coexistence of two-OH groups on a carbon atom
D. Compound is non-planar and polar

Answer

To determine the incorrect statement regarding chloral hydrate (CCl₃CHOH)₂, we will analyze the structure and properties of the compound step by step.

### Step 1: Draw the Structure of Chloral Hydrate
Chloral hydrate has the following structure:

- It consists of a carbon atom bonded to three chlorine atoms (CCl₃).
- This carbon is also bonded to another carbon atom that has two hydroxyl (OH) groups.

The structure can be represented as:
```
Cl
|
Cl - C - C(OH)₂
|
Cl
```

### Step 2: Analyze Each Statement
Now we will evaluate each statement provided in the options:

**Option A:** It exhibits intramolecular hydrogen bonding.
- **Analysis:** The presence of two hydroxyl groups (OH) allows for intramolecular hydrogen bonding between the hydrogen of one OH group and the oxygen of the other. This statement is true.

**Option B:** It has 9 lone pairs and 9 bond pairs.
- **Analysis:**
- Each chlorine atom has 3 lone pairs. Since there are 3 chlorine atoms, that gives us 3 × 3 = 9 lone pairs from chlorine.
- Each oxygen atom has 2 lone pairs. Since there are 2 oxygen atoms, that gives us 2 × 2 = 4 lone pairs from oxygen.
- Therefore, the total number of lone pairs = 9 (from Cl) + 4 (from O) = 13 lone pairs.
- The statement claims there are 9 lone pairs, which is incorrect. This statement is false.

**Option C:** It is stable in spite of the existence of 2 OH groups on a carbon atom.
- **Analysis:** The presence of two hydroxyl groups allows for strong hydrogen bonding, which contributes to the stability of the compound. This statement is true.

**Option D:** The compound is non-planar and polar.
- **Analysis:** The carbon atoms in chloral hydrate are sp³ hybridized, which results in a tetrahedral geometry, making the compound non-planar. Additionally, the presence of polar OH groups makes the compound polar. This statement is true.

### Conclusion
Based on the analysis, the incorrect statement regarding chloral hydrate is **Option B**, which states that it has 9 lone pairs and 9 bond pairs.

### Final Answer
The incorrect statement regarding chloral hydrate is **Option B**.
