Which of the following is true for carbon monoxide?
Which of the following is true for carbon monoxide?
The correct options are
A It is a colourless and odourless gas
B Carbon monoxide is toxic in nature
C It gives a blue flame when burns in air
D It reacts with metals to form metal carbonyls
To answer this question, let's recall the properties of carbon.
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 reacts with many metals to form metal carbonyls.
4.CO is an important fuel because it involves a considerable amount of heat when it burns in air to give a blue flame.
2CO+O2→2CO2
