O- explain, using relevant diagrams, why NaCl readily dissolves in water but does not dissolve in cyclohexane - sodium chloride is ionic compound - - draw water is polar, and ion-dipole interaction between NaCl and H2O - cyclohexane is non-polar, and therefore cannot form forces of attraction between ions that can overcome strong ionic bonds, only forms dispersion forces.

  • explain, using relevant diagrams, why ethanol readily dissolves in water but
    • hydrogen bonding between ethanol and water is able to overcome teh sum of intermolecular forces.
