Dienes are hydrocarbons which contain two double bonds. Dienes are intermediate between alkenes and polyenes.

Dienes can divided into three classes:

• Unconjugated dienes have the double bonds separated by two or more single bonds.
• Conjugated dienes have conjugated double bonds separated by one single bond
• Cumulated dienes have the double bonds sharing a common atom as in a group of compounds called allenes.

In organic chemistry a conjugated diene is also a functional group.

Alkene: An alkene in organic chemistry is an unsaturated hydrocarbon containing at least one carbon to carbon double bond. The simplest alkenes, with only one double bond, form a homologous series, the alkenes with general formula CnH2n....
