|Section2= |Section3= |Section8= }} Methylidyne (also systematically named hydridocarbon(•)), also called carbyne, is an organic compound with the chemical formula CH• (also written as ()). Methylidyne is the simplest carbyne. It is a highly reactive gas, that is quickly destroyed in ordinary conditions but is abundant in the interstellar medium (and was one of the first molecules to be detected there).〔 Encyclopedia of Astrobiology, Volume 1 edited by Ricardo Amils, José Cernicharo Quintanilla, Henderson James Cleaves, William M. Irvine, Daniele Pinti, Michel Viso. 2011, Springer: Heidelberg 〕 == Nomenclature == The trivial name ''carbyne'' is the preferred IUPAC name. The systematic names ''methylidyne'', and ''hydridocarbon(•)'', valid IUPAC names, are constructed according to the substitutive and additive nomenclatures, respectively. Methylidyne is viewed as methane with three hydrogen atoms removed. By default, this name pays no regard to the radicality of methylidyne. When the radicality is considered, the radical states with one unpaired electron are named ''methylylidene'', whereas the radical excited states with three unpaired electrons are named ''methanetriyl''. 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「Methylidyne radical」の詳細全文を読む スポンサード リンク
