炔烃
炔烃（英语：alkyne）是一类有机化合物，属于不饱和烃。其官能团为碳-碳三键（－C≡C－）。通式CnH2n-2，其中n为非1正整数。简单的炔烃化合物有乙炔(C2H2)，丙炔(C3H4)等。炔烃原来也被叫做电石气，电石气通常也被用来特指炔烃中最简单的乙炔。
炔字是新造字，，左边的火取自“碳”字，表示可以燃烧；右边的夬取自“缺”字，表示氢原子数和化合价比烯烃更加缺少，意味着炔是烷（完整）和烯（稀少）的不饱和衍生物。「炔」的读音同「缺」。
英语百科
Alkyne 炔烃
In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula CnH2n−2. Alkynes are traditionally known as acetylenes, although the name acetylene also refers specifically to C2H2, known formally as ethyne using IUPAC nomenclature. Like other hydrocarbons, alkynes are generally hydrophobic but tend to be more reactive.
