Alkenes
Alkenes are a A 'family' of organic compounds that have the same functional group and similar chemical properties. of A compound that contains hydrogen and carbon only. that contain a carbon-carbon double bond. The number of hydrogen All elements are made of atoms. An atom consists of a nucleus containing protons and neutrons, surrounded by electrons. in an alkene is double the number of carbon atoms, so they have the general formula:
CnH2n
For example, the molecular formula of ethene is C2H4, while for propene it is C3H6.
Here are the names and structures of four alkenes:
Butene has two straight-chained isomers, as the double bond can be placed in two different places or locations:
- but-1-ene (double bond with the first carbon)
- but-2-ene (double bond with the second carbon)
Alkenes are unsaturated, meaning they contain a A covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.. This bond is why the alkenes are more reactive than the Saturated hydrocarbon. A compound of hydrogen and carbon only, with no C=C bonds..
