A 3D model o ethylene, the simplest alkene.

In organic chemistry, an alkene, olefin, or olefine is an unsaturatit chemical compoond conteenin at least ane caurbon–caurbon dooble bond.[1] The wirds alkene an olefin are eften uised interchyngeably (see nomenclatur section ablo). Acyclic alkenes, wi anerly ane dooble bond an na ither functional groups, kent as mono-enes, form a homologous series o hydrocarbons wi the general formula CnH2n.[2] Alkenes hae twa hydrogen atoms fewer nor the correspondin alkane (wi the same nummer o caurbon atoms). The semplest alkene, ethylene (C2H4), wi the Internaitional Union o Pure an Applee'd Chemistry (IUPAC) name ethene, is the organic compoond produced on the lairgest scale industrially.[3] Aromatic compoonds are eften drawn as cyclic alkenes, but thair structur an properties are different an thay are nae conseedert tae be alkenes.[2]
