Dipole-Dipole Interaction & London Dispersion Forces
Dipole-Dipole forces act between molecules possessing permanent dipole moment. Ends of the dipole possess partial charges. This partial charge is
more than unit electronic charge
less than unit electronic charge
equal to unit electronic charge
double the unit electronic charge
The interaction energy of London dispersion force is inversely proportional to the sixth power of the distance between two interacting molecules but their magnitude depends on
charge of interacting particles
density of interacting particles
polarizability of interacting particles
strength of permanent dipoles in the particles
The intermolecular interaction that is dependent on the inverse cube of the distance between the molecules is
ion-ion interaction
ion-dipole interaction
hydrogen bond
dispersion force
