π Bonds

Covalent chemical bonds resulting from the sidewise overlap of two atomic p orbitals, characterized by electron density above and below the axis of the bonded atoms.

π Bonds

Pi bonds occur when two lobes of an orbital on one atom overlap two lobes of an orbital on another atom and electron density is concentrated above and below the plane of the nuclei.

Molecular Orbital

A region of space in a molecule where an electron is likely to be found, formed by the overlap of atomic orbitals from bonded atoms.

Atomic Orbitals

Mathematical functions describing the probable location of an electron around an atom, instrumental in the formation of chemical bonds.
