Question

what is difference between london force and dipole dipole force?

Answer 1

the london force dispersion force is the weakest inter molecular force . the london dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy position that make the atoms form temporary dipole. this force is sometimes called an induced dipole -included dipole attraction.
dipole-dipole force are attractive force between the positive end of one polar molecule and the negative end of another polar molecule

Answer 2

London dispersion forces are a type of force acting between atoms and molecules.They are part of Van Der Waalas forces.The London dispersion force is named after German -American physicist Fritz London.

and

Dipole-dipole forces are attractive forces between the positive end of the polar molecule and the negative end of the another polar molecule.Dipole-dipole forces have strengths that range from 5kK to 20kJ per mole.
