Interpretation:
The delocalization energy of
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 delocalization energy for conjugated molecules is defined as the extra stability that a molecule attains by spreading its electron over the entire molecule. The delocalization of
