For atoms and nonpolar molecules, the London dispersion force is the only intermolecular force, and is responsible for their existence in liquid and solid states.
12.
The relative binding energies of these three geometric configurations of the benzene dimer can be explained by a balance of quadrupole / quadrupole and London dispersion forces.
13.
PTFE is hydrophobic : neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine.
14.
Thus, the London Dispersion Forces between ethane molecules are higher than that between methane molecules, resulting in stronger forces of intermolecular attraction, raising the boiling point.
15.
The interaction between two permanent multipole moments also contributes to the intermolecular force and the first term ( quadrupole-quadrupole ) is as important as the London dispersion force.
16.
Lipophilicity, hydrophobicity, and non-polarity " can " describe the same tendency towards participation in the London dispersion force as the terms are often used interchangeably.
17.
Van der waals interactions include nonpolar interactions ( i . e . London dispersion forces ) and polar interactions ( i . e . hydrogen bonds, dipole-dipole bond ).
18.
London dispersion forces, named after the German-American physicist Fritz London, are weak intermolecular forces that arise from the interactive forces between instantaneous multipoles in molecules without permanent multipole moments.
19.
The strength of London dispersion forces is proportional to the polarizability of the molecule, which in turn depends on the total number of electrons and the area over which they are spread.
20.
London dispersion forces are particularly useful for the function of adhesive devices, because they don't require either surface to have any permanent Dispersive forces are a consequence of statistical quantum mechanics.
