WebJun 14, 2016 · 1 Answer Truong-Son N. Jun 14, 2016 Without making things too complicated, π bonds are formed by sidelong overlap, which means the orbitals have to be aligned side-by-side. One of the two orbitals cannot align any differently to make the bond, even if it is offset/skewed by only a few degrees.

This overlap leads to the formation of a bonding molecular orbital with three nodal planes which contain the internuclear axis and go through both atoms.
