Key Concepts

Bonding and Antibonding Interactions

When atomic orbitals combine, constructive interference creates bonding orbitals that are lower in energy, while destructive interference leads to antibonding orbitals that are higher in energy. The presence of nodes (regions of zero electron density) in antibonding orbitals is key to understanding their instability compared to bonding orbitals.

Pi (?) Molecular Orbitals

Pi orbitals are formed by the side-by-side overlap of atomic orbitals that are oriented perpendicular to the internuclear axis. They have a nodal plane along the bond axis in their bonding form and exhibit different symmetry compared to sigma orbitals, also resulting in antibonding versions when the overlap is out of phase.

Sigma (?) Molecular Orbitals

Sigma orbitals result from head-on or axial overlap of atomic orbitals along the internuclear axis. These orbitals are symmetric about the bond axis, typically possess no nodal plane along that axis in bonding combinations, and can have antibonding counterparts that include a nodal plane.

Atomic Orbital Overlap

Atomic orbitals must geometrically overlap for bonding to occur. The extent and manner of overlap (head-on or side-by-side) determine how effectively the orbitals combine into molecular orbitals, which affects whether the resulting orbital is bonding or antibonding.

Molecular Orbital Theory

This theory describes how atomic orbitals combine when atoms bond to form molecules. Instead of viewing bonds as localized interactions, electrons are delocalized over the entire molecule in molecular orbitals, which can be lower in energy (bonding) or higher in energy (antibonding) relative to the original atomic orbitals.
