antibonding
This term is a specialized technical descriptor used almost exclusively within quantum chemistry and molecular orbital theory. It describes a specific state of electronic interaction where the wave functions of atomic orbitals interfere destructively, creating a node between the nuclei and increasing the system's potential energy.
In a practical sense, the term is used to contrast with bonding orbitals. While a bonding orbital stabilizes a molecule by concentrating electron density between nuclei, an antibonding orbital destabilizes it. This distinction is critical for calculating the bond order of a molecule to determine if a chemical species can exist stably.
Meanings
Examples
The electrons occupy the antibonding orbital when the molecule is in an excited state.
Wait, does adding an electron to the antibonding level weaken the bond?
An antibonding interaction occurs when atomic orbitals combine out of phase.
An antibonding interaction occurs when atomic orbitals combine out of phase.
I need to remember that the antibonding orbital has a node between the nuclei.
The presence of electrons in the antibonding orbital reduces the bond order.
He explained how the antibonding state increases the overall energy of the system.
If both bonding and antibonding orbitals are filled, the molecule will not be stable.
The wavefunctions interfere destructively to create an antibonding orbital.
