Document Summary

Chapter 1 notes part 2: electronic structure and bonding. When a molecule has only one covalent bond, its dipole moment is identical to the dipole moment of the bond. For example, the dipole moment of hydrogen chloride (hcl) is 1. 1. D because the dipole moment of the h cl bond is 1. 1 d. The dipole moment of a molecule with more than one covalent bond depends on the dipole moments of all the bonds in the molecule and the geometry of the molecule. Electrostatic potential maps (often called simply potential maps) are models that show how charge is distributed in the molecule under the map. The colors on a potential map indicate the relative charge distribution in the molecule and, therefore, the degree to which the molecule (or an atom in the molecule) attracts other species. Red, signifying the most negative electrostatic potential, is used for regions that attract electron-deficient species most strongly.
