Identify

5. Chromatographic Features Comparisons: (13 points) a. Identify and indicate ALL bond dipoles in the 4 compounds used in the TLC experiment. Use o+ and - to label the bond dipoles. Draw in any intramolecular hydrogen bonding then draw the interactions of each compound with the silica stationary phase by drawing in SiO2 subunits; use dashed lines to indicate the attractive forces between the molecules and the silica. (Use pages 27 and 99 in the lab guide as guides, see Canvas for a color-coded additional example.) (8 points). H H3C CH3 E CH3 H H
