Assign the NMR peaks below DIRECTLY onto the paper, please!!!! The impurities are water at 2.19 ppm and acetone at 1.6 ppm. So just ignore those peaks. The peaks for the aromatic Hydrogens can be grouped up to one (I believe they are the left most peaks at around 7 to 7.5 ppm. Given that please assign the rest of the hydrogens.

In the proton NMR for benzil, there are clearly some impurity peaks below 8 ppm. Although we cannot assign these for certain, is it possible that these peaks come from unreacted benzoin?

Deduce the structure of this ketone by its proton NMR, and assign the appropriate peaks. The options for the unknown ketone are: 2-butanone, 4-pentanone, 4-methyl-2-pentanone, cyclopentanone, 2-heptanone, d-l, 3-methylcyclohexanone, 2-octanone, cycloheptanone, acetophenone, and butyrophenone. Beside the photo, no additional information was given, including more specific multiplicity of peaks. However, I am almost certain that the correct structure is d-l, 3-methylcyclohexanone, I am just having trouble assigning the peaks. Second Unknown Ketone THS cticiろ 80 75 70 6.5 6.0 5.5 5.0...
