Prelab Questions: 1. In the final product, triphenylmethyl ethyl ether, there is only one oxygen atom. From which of the two starting materials did it come? 2. Calculate the Rr value for the spot on the TLC plate shown below. Measure distances in mm (with a ruler) and show your work. 3. Would you expect an alcohol or an ether to have a higher Rr value on silica gel thin layer chromatography? Why?

Fully explain what the data in IR and GC-MS spectra mean in the dehydration of 2-Methylcyclohexanol . GC-MS data (gas chromatography): Illustrated in picture *ignore peak at 8.87 minutes Peak 1 mass = 96.2 (1-methylcyclohexene) Peak 2 mass = 96.2 (3-methylcyclohexene) Peak 3 mass = 114.2 (impurity) IR Spectra (Infrared Spectroscopy): Illustrated in picture.
How would you interpret this IR spectra of fluorene? What I mean by this is which peaks let you know its fluorene and which peaks show impurities if any such as 9-fluorenone since this lab required a separation of fluorene and 9-fluorenone. Other impurities could be solid alumina and sand and the solvents of pet. ether and dichlormethane.
Your lab instructor overheard your partner’s proposal, and thought it was a good opportunity to illustrate a nifty reaction called the retro-Claisen reaction. She pulls a bottle of Compound X off the shelf, and asks you to dissolve it in methanol and add some sodium methoxide. After the reaction finishes, you purifty the product by column chromatography and analyze it by IR and NMR spectroscopy, and you determine that the product is exactly the compound you started with in part a)!

When you run a TLC plate with methyl orange and biphenyl, you observe very large, broad, streaky spots on the plate under the UV light. What is the most likely explanation? a. The elution solvent was too polar. b. Too much sample was spotted onto the TLC plate. c. Too little sample was spotted onto the TLC plate. d. The elution solvent was not polar enough. e. The Rf of the components was too high.
