Chapter 7 Molecular Geometry and Bonding Theories

Learning Objectives

Chapter 7 Topic 1: VSEPR - Sections 7.1 and 7.2

MLO4-5 Predict the electronic and molecular geometry, bond angles, and polarity using the Valence shell electron pair repulsion model.

Chapter 7 Topic 2: Intermolecular forces - Section 7.3

MLO4-6 Identify the intramolecular (bonding) and intermolecular (attractive) forces between molecules: dipole-dipole, hydrogen bonding, and dispersion forces present in a given substance.

Chapter 7 Topic 3: Valence Bond Theory / Hybrid orbital theory - Section 7.4, 7.5, and 7.6

MLO4-7 Apply hybrid orbital theory to predict the hybridization and explain sigma and pi bonding and resonance in molecules.

Chapter 7 Topic 4: Molecular Orbital Theory (optional) - Sections 7.7 and 7.8

OP-MLO4-8 Explain how atomic orbitals combine to form bonding and antibonding molecular orbitals
