A Pi-bond is a type of covalent bond that is composed of the sideways overlap of two neighbouring P orbitals[1]. P orbitals have a dumb-bell shape and when they overlap to form a Pi-bond the structure consists of one P orbital above the molecular axis and one P orbital below the molecular axis. The Pi-bond is formed from unbound P-orbitals from neighbouring atoms. The Pi- bond is arranged from an unbound electron in the P-orbital of one atom bonding to an unbound electron in the P-orbital of another atom causing the P-orbitals to overlap sideways to form the Pi-bond. A single bond is built up of one sigma bond and no Pi-bonds whereas a double bond is build up of a sigma bond and a Pi-bond[2][3].
