An sp2 hybrid orbital is an orbital formed by the linear combination of one s and two p orbitals of comparable energy (such 2s and 2p orbitals) on a same atom. The three sp2 hybrid orbitals lie in a plane with angle of 120°. The remaining p orbital remains unchanged and is perpendicular to the plane of the three sp2 orbitals.
