Reverse Friction?

Chemical force? What do I mean by this? I am writing about intermolecular forces, the force that 'holds' atom or molecules together. As you know there are three intermolecular forces: Hydrogen bonds (the strongest). Permanent dipole - dipole interactions. Van der Waals / London dispersion forces (the weakest). It is the ...
