Question

why CO is highly poisonous for human

Answer 1

the incomplete burning of fossil fuels such as petrol and diesel leads to the formation of carbon monoxide. carbon monoxide is a highly poisonous gas ,when inhaled it combines with the haemoglobin present in blood to form a stable compound called carboxyhemoglobin and thus lowers the oxygen carrying capacity of blood. breathing in carbon monoxide causes headache dizziness and even lead to death

Answer 2

Explanation:

Carbon monoxide reacts with haemoglobin and form a stable compound carboxyhemoglobin. carboxyhemoglobin is 300 times more stable than oxyhemoglobin. Formation of carboxyhemoglobin reduces the oxygen carrying capacity of the blood,as a result of this suffocation takes place. Low level poisoning results in headache and drowsiness, high level poisoning may cause death.
