Dipole attractions for london dispersion

Illustrate how are dipole attractions London dispersion forces and hydrogen bonding similar?

E

Expert

Verified

They are both forces of attraction used to keep molecules together. As the molecules are the atoms bonded together, there are no electrons, left over to bond with more atoms. The outcome would be trillions of tiny molecules floating about. In its place, each of these types of attractions draws molecules together into solids, gases or liquids.
