  1. Chapter 8Lecture 8.5 Hybridization Section 8.3 Bonding Theories

  2. Molecular Orbitals • an orbital formed by the overlap of atomic orbitals • Bonding orbital • Can be occupied by two electrons in a covalent bond • Sigma Bond • Pi Bond

  3. Sigma Bondσ • Head-on overlap of two atomic orbitals • Has axial symmetry

  4. Sigma BondσHydrogen, H2

  5. Sigma BondσFluorine, F2

  6. Pi Bondπ • Side by side overlap of two orbitals

  7. Ethene
