Explain in detail that what happens to these physical properties as the strength of inter molecular forces increases? Discuss do they increase or decrease?
1. Melting point, boiling point, vapor pressure, surface tension, viscosity
2. Substances with weak intermolecular forces tend to be in the gas state at room temperature. Moderate intermolecular forces are needed to liquefy or solidify a substance at room temperature. Define the types of intermolecular forces as moderate or weak. London dispersion, ion-dipole, Hydrogen bonding, dipole-dipole
3. Determine the predominant type of intermolecular force (London dispersion, dipole-dipole, hydrogen bonding) in each of the following compounds.
CHF3, OF2, HF, CF4
