Incorrect statement about carbon monoxide is :-

Options

A. It is highly soluble in water
B. It burns in oxygen to produce considerabe amount of heat
C. it is toxic having bond order = 3
D. it is found in coal gas, water gas and produces gas

Answer

To determine the incorrect statement about carbon monoxide (CO), we will analyze each statement provided regarding its properties and characteristics.

### Step 1: Analyze the first statement
- **Statement**: Carbon monoxide is highly soluble in water.
- **Analysis**: Carbon monoxide is actually only slightly soluble in water, not highly soluble. Therefore, this statement is incorrect.

### Step 2: Analyze the second statement
- **Statement**: Carbon monoxide burns in oxygen and forms carbon dioxide, releasing a large amount of heat.
- **Analysis**: When carbon monoxide (CO) burns in oxygen (O2), it reacts to form carbon dioxide (CO2) and releases heat. This is an exothermic reaction. Therefore, this statement is correct.

### Step 3: Analyze the third statement
- **Statement**: Carbon monoxide is toxic and has a bond order of three.
- **Analysis**: Carbon monoxide is indeed toxic to humans and animals. The bond order of CO, which has a triple bond (C≡O), is calculated as 3. Therefore, this statement is also correct.

### Step 4: Analyze the fourth statement
- **Statement**: Carbon monoxide is found in coal gas, water gas, and producer gas.
- **Analysis**: Coal gas, water gas, and producer gas all contain carbon monoxide as a component. Therefore, this statement is correct.

### Conclusion
After analyzing all the statements, the only incorrect statement about carbon monoxide is the first one, which claims that it is highly soluble in water.

### Final Answer
The incorrect statement about carbon monoxide is: **It is highly soluble in water.**
