Answer:
London dispersion and hydrogen bonding.
Step-by-step explanation:
Every molecule experienced the london dispersion as an intermolecular force. And remember that hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom where this intermolecular force can be applied to H and a very electronegative atom such as oxygen (O), nitrogen (N), and fluorine (F).
