WebIn benzene, the bond angles are 120°, each carbon has an unhybridized p orbital, which lies perpendicular to the plane of the ring. These p orbitals each have 1 electron inside and there are therefore 6 electrons in the circle of pi orbitals. Benzene has 6 planar sp2 carbons, and therefore each carbon has an unhybridized p orbital.
