Question

Which of the following is the property of carbon monoxide?

• A. Oxidising agent
• B. Catalytic agent
• C. Neutral oxide
• D. Reducing agent
• E. None of the above

Answer 1

The correct option is D Reducing agent

Carbon monoxide is a strong reducing agent. It reduces the oxides of the less active metals to their respective metals and itself gets oxidised to carbon dioxide in the process.

Carbon monoxide is used in the extraction of pure metals from their corresponding oxides.

Hence, option $D$ is correct.
