Dipole moments We know what makes a bond polar: differences in __________________. Polar bonds however, can result in either polar or nonpolar __________. A polar molecule will align itself in an electric field The extent to which a molecule aligns in an electrical field is referred to as the _____ ___________.
Background image of page 2
Dipole moment units = _______ (1 D = 3.34 x 10 - 30 C m). Debytes range from __ ______. In nonpolar molecules, μ = __ while in very polar molecules it is close to __. A _____ dipole moment indicates that one end of the molecule is much more negative (or positive) than the other.

Formal charges on a molecule, even though they might add up to zero, do not indicate how the charge is actually distributed (this depends on the shape or symmetry) of the molecule. Differences in electronegativity can easily be used to determine trend in dipole moments for molecules _________________. Dipole moments
