ORGANIC CHEMISTRY Chapter l p Orbital o sp2-Hybridization Orbital o The three sp orbitals that result from hybridization are directed toward the corners of a regular triangle (with angles of 1200 between them). The p orbital that is not hybridized is perpendicular to the triangle formed by the hybrid spd orbitals 5σ- bonds(1CC,4C-H)andlπ-bond 9 Hydrocarbons whose molecules contain a carbon-carbon double bond are called alkenes Department of Chemistry, Xiamen UniversityORGANIC CHEMISTRY Department of Chemistry, Xiamen University Chapter 1 sp2-Hybridization.
