Question

Explain London forces with examples.

Answer 1

London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, or loosely van der Waals forces) are a type of force acting between atoms and molecules.[1] They are part of the van der Waals forces. The LDF is named after the German-American physicist Fritz London.

The LDF is a weak intermolecular force arising from quantum-induced instantaneous polarization multipoles in molecules. They can therefore act between molecules without permanent multipole moments.

Answer 2

London dispersion forces are a type of Van der Waals force Van der Waals forces occur between molecules intermolecular forces and bind them together through charts London London dispersion forces Agar where there is no permanent charge dipole therefore there are no permanent attractions between positive and negative charges instead what occurs are fluctuation of the location of the electrons around the nucleus that give rise to a temporary dipole when this occurs it can also include a temporary dipole in adjacent atoms or molecules leading to and intermolecular attraction because of this depends on the amount of asymmetry it becomes stronger and larger atoms and molecules so this force can start to dominate moving down the periodic table
