Subjective Questions 1. Why is benzene soluble in toluene but not in water? Sol. “ Like dissolves like”. Benzene and toluene are non-polar; H 2 O is polar. 2 . Explain, why solute-solute, solvent-solvent and solute-solvent interactions are important in determining the extent to which a solute dissolves in a solvent? Sol : In the dissolution process, solute – solute, solvent – solvent interactio n overcom e and solute – solvent interactions are overcome and solute – solvent i nteractions are established. The solubility of a solute thus, depends on the strength of new solute – solvent interactions relative to the strengths of solute – solute and solvent – solvent interactions. 3. Indicate the type of solute – solvent inter mole...
