Document Summary
Intermolecular forces- the forces that exist between molecules. Assumes both the volume and shape of its container. Assumes the shape of the portion of the container it occupies. 11. 1 a molecular comparison of gases, liquids, and solids. The state of a substance depends largely on the balance between the kinetic energies of the particles and the interparticle energies of attraction. The strengths of intermolecular forces of different substances vary over a wide range, but they are generally much weaker than ionic or covalent bonds. Exists between an ion and the partial charge on the end of a polar molecule. Are dipoles because they have one positive end and one negative end. Are effective only when polar molecules are very close together. When we examine various liquids, we find that: for molecules of approximately equal mass and size, the strengths of intermolecular attractions increase with increasing polarity. There can be no dipole-dipole forces between nonpolar atoms and molecules.
