Which Of The Following Is True Of Nonpolar Molecules_
dipole moment for the pair, and is denoted p. Suppose we form an electric dipole by placing a charge +q at (0, 0, d/2) and a charge −q at (0, 0, −d/2). (So the dipole moment p has magnitude p = qd and points in the +k direction.) One can show that when z is much larger than d, the electric field for points on the z axis is Ez = 1 2π 0 p ...
The third and dominant contribution is the dispersion or London force (fluctuating dipole–induced dipole), which arises due to the non-zero instantaneous dipole moments of all atoms and molecules. Such polarization can be induced either by a polar molecule or by the repulsion of negatively charged electron clouds in non-polar molecules.

A dipole moment is the turning force a fixed charge has on a dipole in a molecule. The moment depends on the charge at the end of the dipole and its distance from the charge at the other end of the dipole (i.e., the separation of charge).
For other bond angles (120 to 90º) the molecular dipole would vary in size, being largest for the 90º configuration. In a similar manner the configurations of methane (CH 4) and carbon dioxide (CO 2) may be deduced from their zero molecular dipole moments. Since the bond dipoles have canceled, the configurations of these molecules must be ...
OF2 has a bent structure so it has a dipole moment. PF3 has no dipole moment, because it has a pyramidal structure and the withdraing effect on two F atoms is cancelled out by the one F atom at the...
The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.
cancel out, but produce a net dipole (i.e., a polar molecule). OR because, if the molecule had a trigonal planar structure, the molecule would be symmetric with dipoles that cancel out and produce a net dipole of zero (i.e., a nonpolar molecule), which is not consistent with the observation that the ClF 3 molecule does have a dipole moment.
