Study Notes
Bonding Types and Molecular Orbitals
- π bonds always exist with σ bonds, as they are formed perpendicular to the σ bond.
- π bonds are formed when parallel p-orbitals overlap sideways.
- The stability of the resulting molecule in molecular orbital formation depends on the energy of the molecular orbitals.
- π*-orbitals have one nodal plane.
- px and pz atomic orbitals generate σ2p molecular orbitals.
- Atomic orbitals that take part in the formation of chemical bonds by in-phase combination are σ-orbitals.
- In σ molecular orbitals, the electron density is higher and the energy is lower.
- σ and π bonds are distinguished by their orientation relative to the bond axis, with σ bonds being parallel and π bonds being perpendicular.
- The in-phase combination of atomic orbitals may form a σ bond.
- A π covalent bond is formed by the lateral overlap of orbitals.
