Hydrogen polyoxide

Hydrogen polyoxides (also known as oxidanes, oxohydrogens, or oxyhydrogens) are chemical compounds that consist only of hydrogen and oxygen atoms, are bonded exclusively by single bonds (i.e., they are saturated), and are acyclic (have molecular structures containing no cycles or loops).

The simplest possible stable hydrogen polyoxide (the parent molecule) is water, H2O.

The general structure of the class of molecules is some number of oxygen atoms single-bonded to each other in a chain.

Examples include the hydroxy (oxidyl) and hydroperoxy (dioxidanyl) groups.

The ions can also be formed by protonation or deprotonation of various neutral hydrogen polyoxide by suitably strong other acids or bases.
