What are some examples of Alkenes?
Alkenes are molecules containing a carbon-to-carbon double bond, C=C. They form a family of molecules, a homologous series, with general formula
Starting with the simplest, the members of the family are:
,,, actually there are two different molecules, isomers of each other, with the formula
and so on with increasing numbers of carbon atoms.
In the natural world, alkenes are very common. Alkenes are referred to as 'unsaturated' and this is the origin of terms such as monounsaturates (containing one C=C) and polyunsaturates (containing more than one C=C) relating to oils and fats, for example.
