What does alkene mean as a name of something?

noun - plural: alkenes

  1. any unsaturated aliphatic hydrocarbon
    • lexical domain: Substances - nouns denoting substances
    • synonyms of alkene: olefin / olefine
    • more generic term: aliphatic compound = organic compound that is an alkane or alkene or alkyne or their derivative
    • more specific words: ethylene / ethene = a flammable colorless gaseous alkene; obtained from petroleum and natural gas and used in manufacturing many other chemicals


Alkene: In organic chemistry, an alkene, olefin, or olefine is an unsaturated hydrocarbon 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.
