Ion dipole interaction energy
WebFrom the formula, it is clear that Ion-ion interaction energy is inversely proportional to the distance between ions i.e E ∝ 1 r. Step 2: Dipole-dipole. The energy of the dipole-dipole interaction between polar molecules in solids is inversely proportional to 1 r 3. Dipole-dipole interaction energy ∝ 1 r 3; Step 3: London dispersion Webneither molecule is an ion. Such dipole-dipole interactions occur because of electrostatic attraction between the partially positive atom of one polar bond and the partially negative …
