The strongest intermolecular force between solute and solvent in the solution of dimethyl ether in water is to be determined. Concept introduction: The solution is a homogenous mixture that is formed from two or more substances. It consists of two components, solute, and solvent. The substance that is present in a smaller amount and is dissolved in the other substance is called solute. The solvent is that substance which is present in a larger amount and it dissolves solute in itself. The intermolecular forces are the forces that act between molecules, atoms or ions. They are relatively weak forces of attraction. These are of five types as hydrogen bonding, ionic bonding, ion-dipole forces, ion-induced dipole forces, van der Waals forces.
