Question

What is the interaction energy associated with the London force?

Answer 1

Hint :To answer this question we should have the knowledge of the energy we are talking about and especially of the London force. The London force was invented by the scientist named Fritz London in$1930$. He gave the explanation of the attraction between noble gas atoms. The detailed answer is given below.

Complete Step By Step Answer:
The interaction energy associated with London forces is inversely proportional to the sixth power of the distance between the two interacting particles. They are also known as dispersion forces and they are the weakest type of intermolecular bond. This type of bond exists between all atoms and molecules. The main reason for the existence of this force is due to the uneven distribution of electrons within an atom and due to this distribution the atom acquires slightly positive charge and slightly negative charge on either side of it. In this way not permanent but a temporary dipole gets established. London forces or dispersion forces always depend upon the size of the molecule or an atom. Larger the size of atoms and molecules, more the number of electrons are there and larger dipoles get established.

Note :
London forces or dispersion forces are directly proportional to the size of the atom. Greater the size of the atom, the larger the force will be. The molecules which can be easily polarized achieve stronger London dispersion forces whereas on the other hand the molecules which do not get polarized easily achieve weaker London dispersion forces.
