Molecular Polarity and Valence Bond Theory

This lecture covers the concept of molecular polarity, discussing how polar bonds and unsymmetrical shapes lead to polar molecules affecting intermolecular forces. It also explores net dipole moments in molecules like HCl, CO₂, and H₂O. Furthermore, it delves into the limitations of Lewis theory in predicting properties and introduces the Valence Bond Theory, explaining how orbital overlap and hybridization play a crucial role in forming chemical bonds.
