翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hydrogen polyoxide ： ウィキペディア英語版 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 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. The oxygen atom at each end of this oxygen skeleton is attached to a hydrogen atom. Thus, these compounds form a homologous series with chemical formula 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). An oxidanyl group is a functional group or side-chain, that like a hydrogen polyoxide, consists solely of single-bonded oxygen and hydrogen atoms, for example a hydroxy (oxidyl) or hydroperoxy (dioxidanyl) group. ==Specific examples== Hydrogen polyoxides containing up to five oxygen atoms have been produced experimentally. *Water (H2O) is the most common hydrogen polyoxide, occurring widely on Earth's surface. *Hydrogen peroxide (H2O2) is a common disinfectant and readily decomposes to form water and oxygen. *Trioxidane (H2O3) is rare and readily decomposes into water and singlet oxygen. *Hydrogen tetroxide (H2O4) has been synthesized by reaction among peroxy radicals at low temperature. *Hydrogen pentoxide (H2O5) is a byproduct of trioxidane production〔Xin Xu and William A. Goddard III. Peroxonechemistry: Formation of H2O3 and ring-(HO2)(HO3) from O3/H2O2〕 and has also been synthesized by reaction among peroxy radicals at low temperature.〔 Hydrogen polyoxides containing up to 10 oxygen atoms have been studied theoretically, but those containing more than five oxygens are expected to be extremely unstable. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hydrogen polyoxide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
