coordinated bond (covalent)
The bond between nitrogen and oxygen in this compound is a double bond which is covalent.
Hemoglobin contains iron atoms that bind to oxygen molecules. This iron atom within the heme group forms a reversible bond with oxygen, allowing hemoglobin to efficiently transport oxygen throughout the body.
A phosphodiester bond is the type of bond that is present between phosphorus and oxygen in a DNA molecule. This bond forms between the phosphate group of one nucleotide and the hydroxyl group of another nucleotide, linking the nucleotides together in a DNA backbone.
When oxygen and iron bond, it forms an ionic bond. Iron tends to lose electrons, becoming positively charged, while oxygen gains electrons, becoming negatively charged. This attraction between the oppositely charged ions creates an ionic bond.
Carbon (IV) oxide, also known as carbon dioxide, contains covalent bonds between the carbon and oxygen atoms. The double bond between the carbon and one of the oxygen atoms is a covalent bond, while the single bond between the carbon and the other oxygen atom is also a covalent bond.
The rise of temperature denatures the bond between oxygen and hemoglobin.

This is not the main reason:The molecular mass of CO is 28 a.m.u while that of O2 is 32 a.m.u therefore the rate of diffusion of CO is higher than O2 and it enter fast into respiratory track and lungs and causes the deficiency of oxygen.Added:(The more important reason is):CO is about 200 times more reactive to 'ferro'-hemoglobin than O2, so it can hardly be replaced by the available excess of oxygen in air, thus preventing the life-essential O2-transfer to parts of the body like brains and hart & lung muscles.(Cf.

covalent bond
There are two pi bonds present in CH3NO2. One pi bond is between the carbon and nitrogen atoms, and the other pi bond is between the nitrogen and oxygen atoms.
