What is an Alkene?
Alkenes form an homologous series with the
general formula CnH2n.
|Methene, CH2, does not exist.||Butene, C4H8, has n=4.|
|Ethene, C2H4, has n=2.||Pentene, C5H10, has n=5.|
|Propene, C3H6, has n=3.||Hexene, C6H12, has n=6.|
Below are links to the
structure of alkenes.
Some of these exist as isomers.

Alkenes are hydrocarbons which have
double bond between two of the carbon atoms.
They do not have the maximum number of hydrogen atoms
for the number of carbon atoms present
(they have two less than the same alkane)
and so alkenes are called unsaturated hydrocarbons.
See also the uses of alkenes.
