The London dispersion force is the weakest of thevan der Waals forcesand is the force that causesnonpolaratoms or molecules tocondenseintoliquidsorsolidsas thetemperatureis lowered. Even though it is weak, of the three van der Waals forces (orientation, induction, and dispersion), the dispersion ...

In materials with dipole molecules, the other Van der Waals forces dominate, but for materials made up completely of neutral molecules, London dispersion forces are the only active intermolecular forces. Examples of materials made up of neutral molecules include the noble gases such as neon, argon...

London dispersion forces are the weakest component of Van der Waals interactions. They arise from attractions between instantaneously induced dipoles on neighbouring atoms. Their relative weakness, in particular for light atoms, such as hydrogen, has led to their importance being largely ignored in disc...
Dispersion Forces - Introduction Dispersion force arises because of the fluctuation in the polarizability. It is a temporary effect. The noble gases that don't form any chemical bonds are attracted to each other and condense to liquid form at low tempera

Tags Forces Intermolecular forces In summary, the strongest intermolecular force is hydrogen bonding, followed by dipole-dipole interactions and then London dispersion. This can be determined by looking at the molecule's polarity and the presence of hydrogen bonded to F, O, or N. Metallic bon...
