PC1001 Lecture Notes - Lecture 10: Anatomical Terms Of Location, Noxious Stimulus, Muscle Spindle

I am needing to know how these bath temperatures are obtained, Ihad them written down in my lecture/lab notes but I lost the entirebinder and could not remember the conditions necessary for the bathtemps. I striking suspicion that these may turn up on my laboratoryexam, anyways thanks in advance :-)

-78^o C

-95^oC

-110^o to 111^oC

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!
