Suggest a reason as to why $CO$ is poisonous.
(N/A) $CO$ is highly poisonous because of its ability to form a complex with haemoglobin $(Hb)$.
The $CO-Hb$ complex is about $300$ times more stable than the $O_2-Hb$ complex.
This stability prevents $Hb$ from binding with oxygen,leading to oxygen deficiency in the body.
Consequently,a person dies due to suffocation.
