烷烃 Alkane

(重定向自Paraffins)
图中为最简单的烷烃类--甲烷(CH4)。此化合物仅由碳和氢组成,并且全由单键连接,符合烷烃类的特色。[1]
人工合成的正十二面体烷C20H20
环丙烷,化学式为C3H6[36]
例二,双环[2.2.1]庚烷(俗称降冰片烷)

烷烃英语:alkane),又称石蜡烃,是碳氢化合物下的一种饱和烃,其整体构造大多仅由碳、氢、碳-碳单键与碳氢单键所构成,同时也是最简单的一种有机化合物,而其下又可细分出链烷烃与环烷烃。其名是化学家取「碳」右下角之「火」,加上「完」以造出的字,读音同「完」。「碳」表示其结构中含有碳,而「完」表示其分子结构中碳原子化合价完足的意思。

Alkane 烷烃

(重定向自Paraffins)
Chemical structure of methane, the simplest alkane
 Different C4 alkanes and cycloalkanes (left to right): n-butane and isobutane are the two C4H10 isomers; cyclobutane and methylcyclopropane are the two C4H8 isomers. Bicyclo[1.1.0]butane is the only C4H6 compound and has no isomer; tetrahedrane (below) is the only C4H4 compound and also has no isomer.
Ball-and-stick model of isopentane (common name) or 2-methylbutane (IUPAC systematic name)
Melting (blue) and boiling (orange) points of the first 16 n-alkanes in °C.

In organic chemistry, an alkane, or paraffin (a historical name that also has other meanings), is a saturated hydrocarbon. Alkanes consist only of hydrogen and carbon atoms and all bonds are single bonds. Alkanes (technically, always acyclic or open-chain compounds) have the general chemical formula CnH2n+2. For example, methane is CH4, in which n = 1 (n being the number of carbon atoms). Alkanes belong to a homologous series of organic compounds in which the members differ by a molecular mass of 14.03 u (mass of a methylene group, —CH2—, one carbon atom of mass 12.01 u, and two hydrogen atoms of mass ~1.01 u each). There are two main commercial sources: petroleum (crude oil) and natural gas.
