This study guide contains over 3 hours of recorded lecture topics and example problems that follow the material covered in chapter 11 of the textbook Chemistry, The Molecular Nature of Matter and Change by Silberberg. The topics covered include:
Valence bond theory: orbital overlap, pairing of electron spins and hybridization as a means of accounting for the bonding and shapes of molecules.
Mixing orbitals wave functions to form hybrid orbitals with different spatial orientations.
Viewing end-to-end and side-to-side overlap as the origin of sigma (σ) and pi (π) bonds in simple molecules.
How two modes of atomic and hybrid orbital overlap lead to single, double, and triple bonds.
How π bonding restricts the rotation around double bonds.
Differences between the localized bonding of VB theory and the delocalized bonding of molecular orbital (MO) theory.
How addition or subtraction of AO wave functions generates bonding or anti-bonding MOs.
Accounting for the shapes of MOs formed from combinations of two s orbitals and combinations of two p orbitals.
How MO bond order predicts the stability of diatomic molecules and their ions.
Using the MO theory to explain the bonding and properties of homonuclear diatomic molecules of Period 2.
