Multiple Bonds s and p Bonding in C2H4

• The extra p orbital electron on each C atom overlaps the p orbital on the neighboring atom to form the p bond.

C atom orbitals are COMBINED

(= re-hybridized) to form orbitals

better suited for BONDING

• The 3 sp2 hybrid orbitals

are used to make the C-C

and two C-H ? bonds
