Question

The poisonous nature of carbon monoxide (CO) is due to its

insolubility in water
ability to form a complex with haemoglobin
ability to reduce some metal oxides
property of having one sigma bond

Answer 1

Answer:

The correct option is B.

Explanation:

♦ Carbon monoxide is poisonous. It binds to haemoglobin to form carboxyhaemoglobin, which is about 300 times more stable than the oxygen-haemoglobin complex.

♦ In blood, when the concentration of carboxyhaemoglobin reaches about 3 to 4 per cent, the oxygen carrying capacity of blood is greatly reduced. This oxygen deficiency, results into headache, weak eyesight, nervousness and cardiovascular disorder. This is the reason why people are advised not to smoke.

Answer 2

Answer:

because it has more affinity towards Haemoglobin than O2 200 times.

Hence it's poisonous as it's ability to form complex with Haemoglobin.
