Explanation:
Answer: London dispersion forces (i.e LDF), also known loosely Van dear Waals forces.
Explanation: The London dispersion forces is named after the German - American physicist called Fritz London.
The London dispersion forces describes the interaction between two atoms A and B after London discovered the "quantum mechanical theory".
London dispersion theory is similar to the quantum mechanical theory of "light dispersion", that is why it is called "dispersion effect". In Physics,dispersion can be explained as the variation of a quantity with frequency, which is the fluctuation of the electrons in the case of the London dispersion.
