8.3 Molecular Orbitals • A Sigma Bond
8.3 Molecular Orbitals • Pi Bonds • In a pi bond (symbolized by the Greek letter ), the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms.
8.3 Molecular Orbitals • Pi-bonding Orbital
8.3 VSEPR Theory • VSEPR Theory • How does VSEPR theory help predict the shapes of molecules?
8.3 Hybrid Orbitals • Hybrid Orbitals • In what ways is orbital hybridization useful in describing molecules?
8.3 Hybrid Orbitals • Orbital hybridization provides information about both molecular bonding and molecular shape. • In hybridization, several atomic orbitals mix to form the same total number of equivalent hybrid orbitals.
8.3 Hybrid Orbitals • Hybridization Involving Single Bonds
8.3 Hybrid Orbitals • Hybridization Involving Double Bonds
8.3 Hybrid Orbitals • Hybridization Involving Triple Bonds
Hybrid Orbitals • Simulation 7 Compare sp, sp2, and sp3 hybrid orbitals.

8.3 Section Quiz. • 1. A molecular orbital belongs to a • specific atom. • molecule as a whole. • specific pair of atoms. • central atom.
8.3 Section Quiz. • 2. VSEPR theory enables prediction of 3-dimensional molecular shape because the valence electron pairs • are attracted to each other. • form molecules with only four possible shapes. • stay as far apart as possible. • always form tetrahedral shapes.
8.3 Section Quiz. • 3. Orbital hybridization provides information about • both molecular bonding and molecular shape. • both molecular bonding and bond energy. • neither molecular bonding nor molecular shape. • neither molecular bonding nor bond energy.
