Which of the following is/are true for carbon monoxide?
Which of the following is/are true for carbon monoxide?
The correct options are
A It is a colourless gas.
C It gives a blue flame when burnt in air.
D It is toxic in nature.
1. Carbon monoxide is a colourless and odourless gas.
2. CO is toxic in nature as it reacts with haemoglobin in the blood and forms a complex called carboxyhaemoglobin which is about 300 times more stable than the complex formed by the reaction of oxygen(air) and haemoglobin in the lungs.
Haemoglobin + CO → Carboxyhaemoglobin.
Haemoglobin + O2⇌ Oxyhaemoglobin.
This prevents the haemoglobin present in the RBC (red blood cells) from carrying oxygen from the lungs to all parts of the body. This leads to oxygen deficiency causing unconsciousness ultimately leading to death.
3.CO burns with a blue flame to produce carbon dioxide.
2CO(g)+O2(g)→2CO2(g)
