2 Molecular Geometries

3 What is it? The three dimensional arrangement of atoms in a molecule (i.e. covalent compounds) Determined by the bonding pairs of electrons (shared) and the lone pairs of electrons (non- bonding pairs) We predict the 3-D shape using VSEPR Valence-Shell Electron-Pair Repulsion
