Learning Outcomes for Exam 3

Learning Outcomes for Bonding

Note: Outcomes 1-13 were supposedly covered on Exam 2. However, you still need to know most of that in order to proceed with 14-22 shown here for Exam 3.
Concepts not directly on the exam are muted to a faint gray color.

Students will be able too...

  1. Identify metals and non-metals, and predict the types of compounds (ionic/covalent) that will form from different elements.
  2. Distinguish between molecules, ions, and atoms.
  3. Predict the anion or cation that a main-group element is likely to form.
  4. Relate Coulomb’s law to ionic radii, ionic charge, and lattice energy.
  5. Describe the distance dependence of the potential energy of a covalent bond.
  6. Predict and explain relative bond strength and lengths in a compound.
  7. Name and write formulas for covalent compounds.
  8. Interpret line drawings of chemical compounds with implicit hydrogens, carbons, and lone pairs.
  9. Rank the polarity of covalent bonds based on relative electronegativity.
  10. Define dipole moment and identify polar bonds.
  11. Draw the best Lewis structure (including any resonance structures) for a molecule or polyatomic ion.
  12. Apply formal charges to structures and use them to predict the most likely structure.
  13. Recognize and apply exceptions to the octet rule. (for the purpose of identifying the geometries)
  14. Apply the VSEPR model to determine a molecule's electronic and molecular geometry based on its Lewis dot structure.
  15. Assess if a molecule is polar based on polar bonds and its molecular geometry.
  16. Identify the orbital hybridization for any atom in a given molecule using the VB model.
  17. Describe the type of bond (e.g. sigma, pi) and the atomic orbitals that are associated with the bond using the VB model.
  18. Differentiate between localized and delocalized electrons within a structure.
  19. Diagram orbital hybridization using orbital notation.
  20. Recognize that Molecular Orbital (MO) theory is used to determine the energy of the electron in a molecule as well as its geometry.
  21. Differentiate between constructive interference and destructive interference of atomic orbitals.
  22. Construct and fully interpret a MO diagram, including identifying the bond order, the lowest energy electronic excitation energy (HOMO-LUMO gap), and the magnetism (paramagnetic or diamagnetic) for a compound.

Learning Outcomes for IMFs

Students will be able to...

  1. Define the three major intermolecular forces (IMFs) that can exist in condensed phases: dipole-dipole interaction, hydrogen bonding, and dispersion forces.
  2. Associate and rank the potential energies (kJ/mol) of all inter- and intra- molecular forces.
  3. Predict the types of IMFs that a compound can exhibit based on its structure.
  4. Using bonding theories and IMFs, predict the chemical and physical properties of organic materials.
  5. Explain how size, shape, and polarizability affect the magnitude of dispersion forces.

Learning Outcomes for Liquids

Students will be able to...

  • Relate the IMFs of a compound to liquid properties such as boiling point, vapor pressure, viscosity, surface tension, and capillary action.
  • Know and use the terms cohesive forces and adhesive forces to explain phenomena like meniscus formation and capillary action.
  • Correctly rank compounds according to their physical properties based on the IMFs that are present.
  • Explain how liquid properties vary (increase or decrease) with temperature.

    Just focus on the material listed ABOVE.

    Learning Outcomes for Solids

    Students will be able to...

  • Fully describe (atomic arrangement/microscopic view) and visually depict the four types of solids (covalent network, ionic, metallic, molecular).
  • Categorize each solid type based on analysis of their physical properties such as melting point, hardness, ductility, and electrical conduction.
