Share. By Anne Marie Helmenstine, Ph.D. Definition: A pi bond is a covalent bond formed between two neighboring atom's unbonded p-orbitals. An unbound p-orbital electron in one atom forms an electron pair with a neighboring atom's unbound, parallel p-orbital electron.This electron pair forms the pi bond.hare.

In organic chemistry sigma bonds (Ï) are always the first bond between two atoms, resulting from overlap along the bonding axis (of hybrid orbitals), while pi bonds (Ï) are second and third bonds resulting from the overlap of p orbitals, above and below (or in front and back of) the bonding axis.
