CH110 FA11 SAS 2 By the end of Today’s Lecture you should know: Valence Bond Theory (molecular orbitals) Sigma bonds Pi bonds Classifications of hydrocarbons KEY QUESTIONS: THE BIG PICTURE Are all covalent bonds the same? What is the difference between a σ bond and a π bond? What is an organic molecule? What are the major types of hydrocarbons and what bonds do they contain? Remember: structure affects function! How is VSEPR theory used to predict organic bond geometry? How is valence bond theory used to predict organic bond geometry? Chapter 9: Molecular Geometry and Bonding Theories with examples from Chapter 25: Organic Chemistry

CH110 FA11 SAS 3 A. Atomic orbitals: electronic structure in atoms B. Lewis structures: accounting for valence electrons and locating them in bonding pairs or lone pairs C. VSEPR: spatial distribution of e - and shape of the molecule But how do we describe the electron distribution in molecules? D. Valence Bond Theory Extension of Lewis theory Bonds formed when orbitals on adjacent atoms overlap More overlap = stronger bond E. Molecular Orbital Theory but you won’t learn it until Chem 112. (OK, use in 110)
