What would be the expected IR spectrum of meso-tetraphenylporphyrin?
Synthesis of Aspirin Lab Quesitons 1. what major change in the IR spectrum would be expected upon conversion of salicylic acid to acetyl salicylic acid? 2. what purpose did the sulfuric acid serve in this reaction? what would happen if you used phosphoric acid, H3PO4 instead? 3. pick a prescription drug that you or your friends use. describe how it was synthesized

Discuss the IR spectrum and what is the peak in IR that you can see for a specific functional group of the product? Discuss 1H NMR spectrum. Assign and interpret each peak. How do you determine the formation of the product using 1H NMR? IR Spectra 75 70 65 60 Transmittance 56 50 45 46 35 4000 3500 3000 1600 1000 2500 2000 Wenumbers (on 1) HNMR spectra Cheap
Examine your molecule and make predictions about the IR spectrum. Relate expected signals to structural features present. НО НО
8. (1 pt.) A student wants to run an IR spectrum of a sample. The student knows that the sample is an aromatic ketone, but gets the spectrum shown below, which is not of an aromatic ketone and not what they expected. The student was in a hurry and forgot to do something important when running the spectrum. Based on the functional group you see in the spectrum, what did they forget to do? 18 8. (1 pt.) A student...
