7.03 | MO Diagrams of Lewis Acid/Base Adducts

Sunday June 30th, 2024 | In this lesson we investigate the reactivity of Lewis Acid and Lewis Basis, by analyzing their frontier orbitals. In particular we looked at the MO diagram of triphenylphosphine and bromine. After successfully constructing their MO diagrams we identified their frontier orbitals (HOMO and LUMO), and constructed a new MO-diagram of the Lewis Acid/Base adduct by interacting the HOMO/LUMO of each fragment, taking into account their symmetry and energy. We later expanded this concept by analyzing the MO diagram of nitric oxide (NO) in order to determine that is the most likely site of protonation. The in-class exercises and the answer key is attached in the materials section of this lesson
