In Experiment 4, Whittling Down the Possibilities , my class and I used the boiling points, molecular dipole moments, densities, and solubility information of various compounds to determine their identity. For every unknown liquid we tested for a molecular dipole moment. To do so we rubbed a plastic rod with a piece of fabric and released about 1 mL of the unknown liquid on top of the rod using a pipette. If the liquid diverted from the rod than the compound had a molecular dipole moment and if not then there was no dipole moment. Afterward, we tested for the solubility of the compound in water. We mixed the unknown liquid with distilled water and if two layers formed than the unknown was immiscible or at least partially immiscible. If the unknown was not soluble we tested its density relative to water and if it was soluble we could not test its density relative to water. To test the density of the unknown relative to water we took the top layer of the insoluble solution and added it to 10 mg of sodium chloride. If the sodium chloride dissolved then the top
