Lab 4 Report The 4 unknowns all appeared clear and viscous. Some elicited a strong minty smell and some had no smell. In order to narrow the possibilities, we had to take into account the possibility of a dipole moment, the solubility in water, the density relative to water, and the boiling point. 1A: Part I revealed that 1A did not have a significant dipole moment, although some polarity was still possible. This meant it could not be any alcohols, dichloromethane, or any atom with a very strong electronegative atom. In Part II we discovered that 1A was not soluble in water and that it was less dense than water. This meant it could only be cyclohexane, heptane, octane, or paraxylene. The boiling point obtained from the reaction was 74°C, which pointed originally towards cyclohexane. However, the true identity of the unknown was paraxylene. The error between experimental and real boiling point can be attributed to both human error and equipment inaccuracy. If the thermometer was above the reflux ring, it would
