Hydrogen Peroxide Bond Type
The chemical bond type of hydrogen peroxide is related to its chemical properties. There are two types of chemical bonds in the molecule of hydrogen peroxide ($H_ {2} O_ {2} $).
One is a polar covalent bond. The electronegativity of hydrogen ($H $) and oxygen ($O $) is different. When the two bond, the common electron pair is biased towards the oxygen atom with high electronegativity, resulting in a polar hydrogen-oxygen bond. This is the $H-O $bond. There are two such polar covalent bonds in the hydrogen peroxide molecule.
The second is a non-polar covalent bond. The $O-O $bond formed between two oxygen atoms forms a non-polar covalent bond because the bonding atoms are the same, the electronegativity is the same, and the common electron pair is not biased to either side.
It is these two types of chemical bonds, polar covalent bonds and non-polar covalent bonds, that together build the unique molecular structure of hydrogen peroxide, which plays a decisive role in its chemical properties such as oxidation and instability.
