Learning Outcomes:

  1. Be able to interpret Reaction Energy Profiles, using appropriate terminology, describing various types of reaction mechanisms for Oh complexes
  2. Understand the relationship between d-electron configuration rate of ligand substitution (inert vs labile)
  3. Be able to predict the effect of oxidation state, ionic radius, sterics, LFAE, incoming ligand, etc on reactions that proceed by various mechanism types (A, I, D, Ia, Td)

Group Activity - TBD
