The video explains VSEPR theory, which predicts molecular shapes based on electron repulsion. It covers various molecular geometries: linear (e.g., BeCl2, CO2), trigonal planar (e.g., BH3, COCl2), tetrahedral (e.g., methane, SiF4), trigonal pyramidal (e.g., NH3), and bent (e.g., water, SO2). Each geometry is described with examples, bond angles, and the influence of lone pairs.
