Solutes successfully dissolve into solvents when solute-solvent bonds are stronger than either solute-solute bonds or . It is important to note that although London dispersion forces are the only IMFs present in nonpolar molecules, they also exist in all other types of substances. From experimental studies, it has been determined that if molecules of a solute experience the same intermolecular forces that the solvent does, the . What type of intermolecular force is responsible for the attraction between an KCl and a water molecule? The intermolecular force present between H2O and KCl is ion-dipole interaction. Ethanol has a hydrogen atom attached to an oxygen atom, so it would experience hydrogen bonding. chemical.

Below are the introduction, body and conclusion parts of this essay. Recall that boiling points are related to IMF strength. An ionic bond will be stronger than a polar bond, so that is why dipole-dipole interaction seems irrelevant, in comparison to ion-dipole forces. The freezing point is the same as the melting point; it takes more energy to melt a solid with stronger intermolecular interactions. Figure \(\PageIndex{2}\) Water (clear liquid) and oil (yellow) do not form liquid solutions.
