Knowledge of concepts is not enough for a learning experience to be meaningful. We should also understand how the concepts we learned on intermolecular forces can be applied to real life situation to get the most out of what we learned. Let us look at this simple situation that will help us realize the advantage of fully understanding intermolecular concepts. Situation: Storage of different substances at home needs careful attention. Alcohol, acetone, and hair sprays, even gasoline should be taken care of to avoid fire. Where should these substances be stored? Why do we need extra precaution in keeping them at home? Relate your answer to intermolecular forces.1. Briey explain whyr water is considered as the universal solvent. 2. Using the concept of IMFA, account for the difference in boiling point and melting point of the following molecular substances: Substance Boiling point [0C] Melting point [0C] Helium gas, He 69 -2?2 Methane, CH4 462 -184 H20 100 Ethanol, CszOH T3
