Topic: Molecular Polarity
Update: 2025-11-25
Description
This episode explores molecular polarity, explaining how electronegativity differences create polar bonds and why molecular geometry determines overall polarity. The hosts distinguish between bond polarity and molecular polarity, showing how symmetrical molecules like CO₂ and CH₄ are nonpolar despite polar bonds, while asymmetrical molecules like H₂O and NH₃ are polar. They conclude with a step-by-step approach for determining molecular polarity using Lewis structures and VSEPR theory.
