VSEPR Theory

• VSEPR theory proposes that each electron group (single bond, multiple bond, lone pair, or lone electron) around a central atom remains as far from the others as possible. • Five electron-group arrangements are possible when two, three, four, five, or six electron groups surround a central atom. Each arrangement is associated with one or more molecular shapes, depending on the numbers of bonding and lone pairs. • Ideal bond angles are based on the regular geometric arrangements. Deviations from them occur when surrounding atoms and/or electron groups are not identical. • Lone pairs and double bonds exert stronger repulsions than single bonds. • Shapes of larger molecules are composites of the shapes around each central atom. #GeneralChemistry #generalchemistry #GenChem1 #VSEPR #MolecularGeometry
