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.

Atoms that are joined by a double bond have one sigma bond and one pi bond. If they are joined by a triple bond they have one sigma bond and two pi bonds. A pi bond is weaker than a sigma bond, but the combination of pi and sigma bond is stronger than either bond by itself.toms that are joined by a double bond have one sigma bond and one pi bond.
