Chemical Bonds

Pi bonds are a type of covalent bond formed by the sideways overlap of atomic orbitals. Unlike sigma bonds, which are formed by the direct overlap of orbitals along the internuclear axis, pi bonds occur above and below the plane of the Sigma bond.

Formation:

Pi bonds are formed when two p orbitals on adjacent atoms align parallel to each other. This alignment allows for electron density to be concentrated above and below the plane of the Sigma bond.
