Best Answer

London dispersion forces are dependent on the motion of electrons, their strength increases with the number of electrons in the interacting atoms or molecules. This means that London forces increase as the atomic or molar mass increases.

What is the difference between dispersion forces and hydrogen bonding?

Yes, hydrogen bonding may be the strongest force but dispersion forces (London dispersion) increases strength in bonds with size. The greater size the greater strength. Therefore, if you have a huge carbon molecule the forces might be stronger than the H-bond.

Is CH3CH2CH3 London dispersion force?

yes, CH4 has London dispersion forces because it is a non-polar molecule and non-polar molecules have London dispersion forces present in them. there are no other forces present in CH4.
