  Explain the solubility rule "like dissolves like" in terms of intermolecular forces that exist in solutions.

Answer:

                  If the intermolecular interactions are similar in both constituents, i.e., solute and solvent then solute, dissolves in the solvent, e.g., polar solutes dissolve in polar solvents and non-polar solutes in non-polar solvents. Thus, the statement 'like dissolves like' proves to be true. e.g., organic compounds dissolve in non-polar organic solvent while polar inorganic compounds (salts) dissolve in polar solvent (water).
