The video tutorial explains the VSEPR theory and its application in determining the molecular geometry of different molecules. It covers the structure of methane, phosphorus pentachloride, and sulfur hexafluoride, highlighting their bond angles and molecular shapes. Methane is described as a tetrahedral molecule with bond angles of 109.5°, phosphorus pentachloride as a trigonal bipyramidal molecule with varying bond angles, and sulfur hexafluoride as an octahedral molecule with 90° bond angles.
