When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules.
Apex------They form temporary, weak dipole attractions between molecules.
Van der waals force is a form of weak interaction between molecules.
Van der Waals forces are usually considered to include
These are electrostatic in nature, and cause an attraction between molecules
To understand dispersion forces, at any given time there will be more electrons on one side of an atom (or on one side of a bond) that the other. This uneven distribution of electrons creates a small dipole moment. This dipole moment will slightly polarize the atoms and bonds around it creating a temporary source of electrostatic attraction. This electrostatic attraction however is not permanent and is therefore weaker than ones you will find in an ionic bond or with hydrogen bonding.
Hope that helps.

van der waal forces are very weak. there are a few types of these forces including overlapping bonds ( triogonal planar , tetrahydral bonds etc )
Electrons are shared between the atoms.
hydrogen bonds
Hold polar molecules together
intermolecular forces D:
London Dispersion Forces
Hydrogen bonding, dipoles, and London dispersion forces.
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.

between molecules the forces are called intermolecular forces, and between the atoms in a molecule they are called inramolecular forces

Intermolecular force holds large numbers of different molecules together.
Within the molecule, covalent bonds hold them together. Between the molecules there can be several different forces. There are dipole-dipole attractions, hydrogen bonds and van der Waals forces. Which of them apply in a particular substance depends on the structure of the molecules.
