Unformatted text preview: Occasionally, it is better to use a model in which electrons in molecules do not reside in orbitals that are localized on individual atoms, but rather in molecular orbitals (MOs) that span the entire structure of the molecule. Most of the time in organic chemistry, the simple valence bond model, hybrid orbitals, and resonance (last several lectures) can be used to understand the structures of molecules. PLEASE READ AND UNDERSTAND THE MATERIAL IN SECTIONS 1.7 AND 1.9 RELATED TO MOLECULAR ORBITAL THEORY !!! THIS MATERIAL SHOULD BE REVIEW FROM GENERAL CHEMISTRY!!! YOU WILL BE RESPONSIBLE FOR THIS MATERIAL, AND YOU SHOULD BE ABLE TO SOLVE THE RELATED TEXTBOOK PROBLEMS!!! (We will discuss specific aspects of molecular orbital theory in lecture, as needed, later on in the course)...
