Which one of the following is properties of CO gas?

Options

A. It is a colourless gas
B. it is an odourless gas
C. it is a neutral oxide
D. All of these

Answer

To determine the properties of carbon monoxide (CO) gas, we can analyze the given properties step by step.

### Step 1: Identify the properties of CO gas
We need to evaluate the following properties:
1. CO is a colorless gas.
2. CO is an odorless gas.
3. CO is a neutral oxide.

### Step 2: Evaluate each property

**Property 1: CO is a colorless gas.**
- Carbon monoxide (CO) is indeed a colorless gas. This property is true.

**Property 2: CO is an odorless gas.**
- Carbon monoxide is also odorless. This property is true.

**Property 3: CO is a neutral oxide.**
- Carbon monoxide is classified as a neutral oxide, meaning it does not exhibit acidic or basic properties. This property is true.

### Step 3: Conclusion
Since all three properties of CO gas are true:
1. CO is a colorless gas.
2. CO is an odorless gas.
3. CO is a neutral oxide.

The final answer is that all of the given properties are correct for CO gas.

### Answer: All of these properties are correct for CO gas.
