Carbon monoxide gas is more dangerous than carbon dioxide gas. Why?

Text Solution

Verified by Experts

Carbon dioxide `(CO_(2))` and carbon monoxide (CO) gases are emitted during the combustion of varioue fuels. Carbon monoxide is poisonous because it is capable of forming a complex with haemoglobin (carboxyhaemoglobin), which is more stable than the oxygen-haemoglobin complex. The concentration range of 3-4% of carboxyhaemoglobin decrease the oxygen-carrying capacity of blood. This result in headaches, weak eyesight, nervousness, and cardiovascular disorders. A more increased concentration may even lead to death.
Carbon dioxide is not poisonous. It proves harmful only at very high concentrations.

When combustion of coal takes place in _______ air, more of carbon monoxide is formed instead of carbon dioxide.

Since coal and petroleum have been formed from bio-mass, in addition to carbon, these contain hydrogen, nitrogen and sulphur. When these are burnt, the products are carbon dioxide, water, oxides of nitrogen and oxides of sulphur. When combustion takes place in insufficient air (oxygen), then carbon monoxide is formed instead of carbon dioxide. Of these products, the oxides of sulphur and nitrogen and carbon monoxide are poisonous at high concentrations and carbon dioxide is a greenhouse gas. Another way of looking at coal and petroleum is that they are huge reservoirs of carbon and if all of this carbon is converted to carbon dioxide, then the amount of carbon dioxide in the atmosphere is going to increase, leading to intense global warming. Thus, we need to use these resources judiciously. of the above mentioned gases, which one is the green house gas and what does it lead to ?

  • The pressure and temperature of 4dm^(3) of carbon dioxide gas are doubled. Then, volume of carbon dioxide gas would be

    A
    `2dm^(3)`
    B
    `3dm^(3)`
    C
    `4dm^(3)`
    D
    `8dm^(3)`

  • Carbon monoxide is a poisonous gas because

    A
    It binds to hemoglobin to form stable compound
    B
    It is carcinogenic in nature
    C
    Both (1) and (2)
    D
    It induces the chance of heart attack

  • Exposure to carbon monoxide (from coal gas) is extremely dangerous and can kill a patient because

    A
    The compound carboxyhaemoglobin (COHb) it forms with heamoglobin can gradually clot the blood resulting in circulatory failure
    B
    COHb reduces the ability of blood for transport oxxygen by ruputring a vast majority of erythrocytes
    C
    COHb greatly modifies the structure of haemoglobin, thus makiing it lose its affinity for oxygen
    D
    None of the above
