Chemical Bonding: Lewis Structures and Molecular Geometries

This lecture covers the concepts of chemical bonding, focusing on Lewis structures and molecular geometries. It explains the rules for drawing Lewis structures, resonance structures, and formal charges. The lecture also delves into dative bonds, hypervalence, and the repulsion model of valence electron pairs (VSPR). The relationship between electron pairs and molecular geometry is explored, including tetrahedral, octahedral, and linear geometries. The lecture concludes with discussions on dipole moments, polarity of molecules, and the determination of molecular geometry based on repulsion figures.
