Hydrogen peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. In dilute solution, it appears colorless. Due to its oxidizing properties, hydrogen peroxide is often used as a bleach or cleaning agent. The oxidizing capacity of hydrogen peroxide is so strong that it is considered a highly reactive oxygen species. Hydrogen peroxide is therefore used as a propellant in rocketry. Organisms also naturally produce hydrogen peroxide as a by-product of oxidative metabolism. Consequently, nearly all living things (specifically, all obligate and facultative aerobes) possess enzymes known as catalyse peroxidases, which harmlessly and catalytically decompose low concentrations of hydrogen peroxide to water and oxygen.
H2O2 adopts a nonplanar structure of C2 symmetry. Although chiral, the molecule undergoes rapid racemization. The flat shape of the anti conformer would minimize steric repulsions, the 90° torsion angle of the syn conformer would optimize mixing between the filled p-type orbital of the oxygen (one of the lone pairs) and the LUMO of the vicinal O-H bond. The observed anticlinal "skewed" shape is a compromise between the two conformers.

A machine Light’s up in the crystal A magic color an animal
Oh Can’t you see Oh can’t you see
It’s dark blue grey cold liquid haze Black gelly hair in my mind
A silver machine never rest The Harry hair show on TV
Oh Can’t you see Oh can’t you see
It’s dark blue grey hair on fire East desire an animal
It’s dark blue grey lover east side The liquid lipstick in the DDR...
Oh can’t you see Oh can’t you see…
