1. The surface of silica gel has a structure shown in the diagram below : ОН OH ОН -0- Si - 0- Si- 0- Si- 0- main body of silica structure Suppose you used a plate coated with silica gel, with propanone, CH;COCH3, as the solvent for thin layer chromatography. Suppose also that the mixture you were trying to identify contained A compound, P, which could form strong hydrogen bonds. A compound, Q, which formed hydrogen bonds, but not as strongly as P. A compound, R, which was polar, relying on dispersion forces and dipole-dipole interactions for its intermolecular attractions. Describe and explain what the chromatogram would probably look like.

3. A pure white crystalline compound was found to melt at 131.5-132.0°C when taken on a melting point apparatus, and on further heating, the liquid was found to start bubbling at ca. 155-160 °C. The capillary containing the melted compound was set aside to cool, and resolidify. When the sample was retried using that same capillary, the sample melted at 120.6-154.5°C, along with some bubbling. What is the cause of the bubbles? Why is the melting point so wide the second time? Explain by stating what you have learned in this laboratory about melting points.
