Those at increased risk include: 1  People with diabetes. 2  People with high blood pressure. 3  People with a family history of kidney failure. 4  People who are 65 years or older. 5  Certain ethnic groups including African Americans, Hispanics, Asians, American Indians.
The dipole moment of a molecule can be predicted by looking at the molecule's structure and the location of the dipoles within the molecule. When a molecule has no dipole moment, it will be nonpolar. A molecule with a dipole moment will be polar.
Polar molecules with NâH, FâH, or OâH bonds exhibit dipole-dipole interactions (including hydrogen bonding) and dispersion forces. (a) (b) (c) (d) What kind(s) of intermolecular forces exist in (a) CCl 4 (l), (b) CH 3 COOH(l), (c) CH 3 COCH 3 (l), and (d) H 2 S(l).Worked Example 12.1 (cont.) Ion (a) (b) (c) (d) Solution (a) CCl 4 is nonpolar, so the only intermolecular forces are dispersion forces.ydrogen bonding only occurs in molecules that contain H bonded to a small, highly electronegative atom such as N, O, or F. Hydrogen Bonding F H F. 1/7/2013 2 Hydrogen Bonding Dispersion forces or London dispersion forces result from the Coulombic attractions between instantaneous dipoles of non-polar molecules.
