CHEM 20L Lecture 1: [1-12] Week 1 Thursday

Any sample T&F questions and matching type questions for microbiology finals - cummulative? My finals is on Thursday night. Thank you

Tentatively identify the lower boiling solvent from the temperature of the first plateau and the ketone or alcohol from the temperature of the second plateau (the approximate boiling point of each component.) Examine the IR of the higher-boiling fraction and determine whether it is an alcohol or a ketone from the characteristic O-H or C=O stretch. Identify which peak in the IR is from the –OH group of the alcohol or the C=O peak from the ketone. Draw the structure of the compound.

Below are 2 different compounds that I need help identifying. I have attached the NMR and IR spectra that we gathered. We have a couple ideas of what they could be and made marks on the spectra but would like an expert's help with finalizing them. The second NMR spectra is supposed to have a peak around 12-14 for a carboxylic acid but did not show up on ours and it was confirmed that it should be there. There aren't any base peaks either, we had to go into this blind. Thank you so much!
