Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Thus, these compounds form a homologous series with chemical formula H 2 O n in which the members differ by a constant relative molecular mass of 16 (the mass of each additional oxygen atom). The number of oxygen atoms is used to define the size of the hydrogen polyoxide (e.g., hydrogen pentoxide contains a five-oxygen backbone).
The characteristic structure of any regular peroxide is the oxygen-oxygen covalent single bond, which connects the two main atoms together. In the event that the molecule has no chemical substituents, the peroxide group will have a [-2] net charge.
The general structure of an organic peroxide. In organic chemistry, organic peroxides are organic compounds containing the peroxide functional group (R−O−O−R′).If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article.
Hydrogen peroxide is not nearly as reactive as these species, but is readily activated and is thus included. [3] Peroxynitrite and nitric oxide are reactive oxygen-containing species as well. Hydroxyl radical ( HO· ) is generated by Fenton reaction of hydrogen peroxide with ferrous compounds and related reducing agents:
The general structure of an organic hydroperoxide with the blue marked functional group, where R stands for any group, typically organic. Hydroperoxides or peroxols are compounds of the form ROOH, where R stands for any group, typically organic, which contain the hydroperoxy functional group (−OOH).
In most of its other compounds, oxygen has an oxidation state of −2. The structure of dioxygen difluoride resembles that of hydrogen peroxide, H 2 O 2, in its large dihedral angle, which approaches 90° and C 2 symmetry. This geometry conforms with the predictions of VSEPR theory. Dioxygen difluoride's structure
This large family of compounds can be divided into ionic and covalent peroxide. The first class mostly contains the peroxides of the alkali and alkaline earth metals whereas the covalent peroxides are represented by such compounds as hydrogen peroxide and peroxymonosulfuric acid (H 2 SO 5).
