Concept introduction:
Dienes are the compounds that contain carbon-carbon double bonds. The term conjugated dienes is used when the double bonds are present alternatively in a hydrocarbon chain. The mathematical function that describes the wave like behavior of the electron in a molecule is expressed by molecular orbital. The physical and chemical properties are found with the help of molecular orbital.

Concept introduction:
The term conjugated dienes is used when the double bonds are present alternatively in a hydrocarbon chain. The mathematical function that describes the wave like behavior of an electron in a molecule is expressed by molecular orbital. The molecular orbital contains nodes and lobes. Nodes are the regions in the molecular orbital of conjugated system in which the adjoining orbital lobes undergoes a phase change.
