Identify the correct statement regarding CO
Correct answer: B. It is a slightly polar molecule
- A. It combines with H₂O to form carbonic acid
- B. It is a slightly polar molecule
- C. It is a powerful oxidizing agent
- D. It is used to prepare aerated drinks
Explanation
The correct answer is that carbon monoxide (CO) is a slightly polar molecule. This is due to the polar covalent bond formed between carbon and oxygen, which results in a small dipole moment. The other options are incorrect: CO does not react with water to form carbonic acid; that is the behavior of CO₂. CO is not a powerful oxidizing agent; it is known for being a reducing agent. Lastly, CO is not used in aerated drinks; CO₂ is the gas used for carbonation in beverages.
