Briefly describe all of the data you have to support your identification. The identity of unknown was acetaminophen. I know this was my unknown because in my picture of The second TLC plate, the spot where letter "c" cacetaminophen was even with the spot of my unknown. A. 4. 20 Do the experimental Rf values match the predicted rate of elution based on the chemical/structural properties of each molecule? Why or Why not? Include structures and describe any deviations. For each molecule The rf values I calculated were very close to the literature values. 13 9 Thin Layer Chromatography: Identification of Organic Compounds Pre Lab Reagent Table Literature Rf MSDS irritany u Dichloromethane A Aspirin BIbuprofen c Acetaminophen D Caffeine MW BP MP 184.9394 39.6°C -97°C 1180, 1989 140cc 135°C 1206.299 157°C 75-77°C. 15111439 420°C 169°C 194,189 113°C 235°C 0.88 0.155 0,56 0.10 Structure CH 2012 1 Ca Hou CB HISO2 .
