Relative Magnitude
Dispersion forces are usually dominant of the three van der Waals forces (orientation, induction, dispersion) between atoms and molecules, with the exception for molecules that are small and highly polar, like of water. The following contribution of the dispersion to the total intermolecular interaction energy has been given:
Molecule pair | % of the total energy of interaction |
---|---|
Ne-Ne | 100 |
CH4-CH4 | 100 |
HCl-HCl | 86 |
HBr-HBr | 96 |
HI-HI | 99 |
CH3Cl-CH3Cl | 68 |
NH3-NH3 | 57 |
H2O-H2O | 24 |
HCl-HI | 96 |
H2O-CH4 | 87 |

Famous quotes containing the words relative and/or magnitude:
“It is an interesting question how far men would retain their relative rank if they were divested of their clothes.”
—Henry David Thoreau (18171862)
“Constancy has nothing virtuous in itself, independently of the pleasure it confers, and partakes of the temporizing spirit of vice in proportion as it endures tamely moral defects of magnitude in the object of its indiscreet choice.”
—Percy Bysshe Shelley (17921822)
