Forbitals
Forbitals are a type of molecular orbital, also known as a bonding orbital or a frontier orbital, that is involved in the formation of intermolecular and interatomic bonds. They are characterized by an increased energy and are typically degenerate, meaning that they have the same energy.
Forbitals play a significant role in the understanding of the reactivity of molecules and the breaking and
Forbitals, when involved in a chemical reaction, often act as entering electrons during nucleophilic addition reactions.
The concept of forbitals is an extension of the understanding of the more well-known term, frontier orbitals.
