What are the most important intermolecular forces? And what are the mechanisms by which these intermolecular forces work? What is hydrogen bonding and how might hydrogen bonding be used to explain the substantial difference in boiling between ethanol CH3CH2OH (grain alcohol) and dimethyl ether (CH3OCH3)? A hydrogen bond is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule. Hydrogen bonds are dipole-dipole forces. The large electronegativity difference between hydrogen atoms and several other atoms, such as fluorine, oxygen and nitrogen, causes the bond between them to be polar. I will look forward to hear from you all on this. Determine intermolecular forces present in molecules and compounds. Explain surface tension, viscosity, and capillary action. Explain vapor pressure, vaporization, sublimation and fusion. Explain heating curves and phase diagrams. Describe crystalline solids.
8. What are intermolecular forces and how do they compare to intra-molecular forces such as ionic or covalent bonding? What impact do intermolecular forces have on the melting point and the boiling point of a substance?
