Intermolecular Interactions: Polar Molecules and Hydrogen Bonds

This lecture covers the principles of intermolecular forces, focusing on dipole-dipole and ion-dipole forces, as well as the formation of condensed phases. It discusses the significance of polar molecules in intermolecular interactions, including hydrogen bonding in biological molecules. The lecture also explores the concept of instantaneous dipoles and London forces, and how they contribute to the overall strength of intermolecular interactions. The role of polarizability and size in predicting the strength of these interactions is highlighted, along with the impact on the boiling and melting points of substances.
