Gary Lam Experiment 3: Identifying an Unknown Using Dipole Moment, Solubility, Density, and Boiling Point Data Discussion: After obtaining our four samples, we weren’t sure about the identity of any of the solutions since they all looked similar. After part 1, we figured out if each of our solutions had dipole moments. 1A didn’t have a dipole, but 2A, 3A, and 4A all had dipoles so we had some idea of the identity of our solutions after the first part. Then we did the solubility test and found that 1A, 3A, and 4A were not soluble in water but 2A was soluble. With these two tests, we narrowed down the possibilities. 1A could be hexane, carbon tetrachloride, cyclohexane, heptane, trifluorotoluene benzene, 2- Bromopentane, octane, or para-xylene. 2A could be acetone, methanol, or ethanol. 3A and 4A could be dichloromethane, ethyl acetate, 1-2 dichloroethane, 1-propanol, or 1- pentanol. With these possibilities in mind, we performed part 3 for 1A, 3A, and 4A since they were not soluble in water. From part 3, we found out that 1A, 3A, and 4A were all

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
