sp2 hybridization: s + px + py + pz → pz + 3 sp2 hybrid orbitals . Only two of the three hybrid orbitals are used for hybridization. One p orbitals remains. The term sp2 means the hybrid orbitals are 1/3 s and 2/3 p. Hybrid orbitals from both carbons form the C-C and C-H single bonds. The left over p orbitals overlap to form the double bond.
