Calculate an ion-ion interaction energy between \(K^+\) and \(Cl^-\) at a distance of 600 pm. Calculate the ion-dipole interaction between H2O and Li+. This sets it apart further from ordinary dipole-dipole bonding, which has no directionality. Dichloromethane is next highest because it participates in dipole-dipole forces. From experimental studies, it has been determined that if molecules of a solute experience the same intermolecular forces that the solvent does, the solute will likely dissolve in that solvent. What would be the intermolecular forces between the molecules of methanetetrol? Start.

So, depression in freezing point of MgCl2 is three times. London dispersion forces, often abbreviated to LDF, are attractive forces between two transient dipoles. Explain why does water have a high specific heat. Liquids that dissolve in one another in all proportions are said to be miscible. Dipole-dipole interaction, specifically, will probably not happen, or they at least won't contribute significantly to IMFs. What is a weak intermolecular interaction? (434 torr) x (5.5508 mol) / (5.5508 mol + 1.1180 mol) = 361 torr, The vapor pressure of pure water at 85oC is 434 torr.
