Answer #1

van der Waal's forces(dispersion forces) are universal in nature in the sense that they are always present between two molecules irrespective of other kinds of forces.

Also, van der Waal's forces are cumulative in nature. This means that two molecules having dipole-dipole forces also interact via dispersion forces. And molecules having H bonding also attract each other through dipole-dipole forces and dispersion forces.
