  VSEPR  • Valence Shell Electron Pair Repulsion  • Used to predict the shapes and polarities of molecules  • Molecular shapes are predicted based on the fact that electron pairs (bonding and lone  pairs) arrange themselves to be as far apart as possible in order to minimize repulsions  Polarity of Molecules  • Nonpolar bonds always produce a nonpolar molecule  • Polar bonds arranged symmetrically around the central atom, produce a nonpolar molecule  • Polar bonds arranged asymmetrically around the central atom, produce a polar molecule
