烯烃

Alkene

在有机化学中,烯烃,烯烃或烯烃是含有至少一个碳 - 碳双键的不饱和化合物。 仅具有一个双键且没有其它官能团(称为单烯)的最简单的无环烯烃形成具有通式C n H 2n的同源系列烃。 它们具有小于相应烷烃的两个氢原子。 最简单的烯烃是乙烯,其具有国际纯粹和应用化学联合会名称乙烯。 在石油化学工业中,烯烃通常被称为烯烃。 对于桥联烯烃,布雷特的规则规定,双键不能放置在桥接环系统的桥头,除非环足够大。 芳族化合物通常被描绘为环状烯烃,但其结构和性质是不同的,它们不被认为是烯烃。 In organic chemistry, an alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon–carbon double bond. The simplest acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula CnH2n. They have two hydrogen atoms less than the corresponding alkane. The simplest alkene is ethylene, which has the International Union of Pure and Applied Chemistry name ethene. In the petrochemical industry alkenes are often called olefins. For bridged alkenes, the Bredt's rule states that a double bond cannot be placed at the bridgehead of a bridged ring system, unless the rings are large enough. Aromatic compounds are often drawn as cyclic alkenes, but their structure and properties are different and they are not considered to be alkenes.

字典中烯烃的定义也叫烯烃,烯烃。 任何具有通式C n H 2n的不饱和脂族烃。 烯烃的其他定义也称为:烯烃。

The definition of alkene in the dictionary is Also called: olefine, olefin. any unsaturated aliphatic hydrocarbon with the general formula CnH2n. Other definition of alkene is Also called: olefine.
