1.	Suggest a reason as to why CO is poisonous.
Answer» Solution :The haemoglobin present in blood is responsible to TRANSFER oxygen inhaled by a PERSON to different tissues of the body. Carbon monoxide combines with the haemoglobin present in the blood to FORM carboxyhaemoglobin which is about 300 times more stable than oxyhaemoglobin complex. This destroys the oxygen carrying capacity of haemoglobin to VARIOUS organs of the body. As a result the person dies of suffocation. `Haemoglobin + CO to underset("300 times more stable than oxyhaemoglobin")("Carboxyhaemoglobin")`
