Consider the following statements with respect to Carbon monoxide(CO):
1. It is a colorless, odorless, and tasteless gas, making it difficult to detect.
2. It is produced due to the incomplete combustion of carbon-containing fuels such as wood, coal, and gasoline.
3. It has a lower Global Warming Potential (GWP) than carbon dioxide (CO2) and is not considered a primary greenhouse gas.
4. It readily binds with haemoglobin in the blood, reducing oxygen transport in the body.

Which of the statements given above are correct?
(a) 1, 2, and 4 only
(b) 2 and 3 only
(c) 1, 2, and 3 only
(d) 1, 2, 3, and 4

ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Carbon monoxide (CO) is a colorless, odorless, and tasteless gas, making it very dangerous as people cannot detect it without sensors.

Statement 2 is correct: CO is produced due to the incomplete combustion of carbon-based fuels such as wood, coal, gasoline, and natural gas. Poor ventilation in enclosed spaces increases CO buildup.

Statement 3 is correct: CO has a lower Global Warming Potential (GWP) than carbon dioxide (CO2) and is not classified as a primary greenhouse gas. However, it can indirectly contribute to global warming by reacting with hydroxyl radicals (OH&bull;) in the atmosphere, reducing their ability to break down methane (CH3), which is a potent greenhouse gas.

Statement 4 is correct: CO binds strongly with haemoglobin in the blood, forming carboxyhemoglobin, which reduces oxygen transport, leading to hypoxia (oxygen deficiency) and potential poisoning.
