Incomplete combustion produces

Incomplete combustion produces

• A. Oxygen
• B. Carbon monoxide
• C. Nitric oxide
• D. Water vapor

Answer: (B)

Incomplete combustion happens when there isn’t enough oxygen for the fuel to burn fully. When that happens, carbon isn’t fully oxidized to carbon dioxide; instead, some carbon bonds with a single oxygen to form carbon monoxide. This partial oxidation is the defining result of incomplete combustion, and carbon monoxide is the most useful indicator of that condition because it indicates fuel is not being burned completely and can be dangerous to health. Oxygen isn’t a product of combustion, so it wouldn’t be produced. Water vapor is produced in both complete and incomplete combustion, so it doesn’t specifically indicate incomplete combustion. Nitric oxide can form in high-temperature flames, but that’s more about flame conditions than the incomplete oxidation process itself, so it isn’t the characteristic product of incomplete combustion.
