Question

. Here is the NMR of the ethyl acetate. We combined all the fractions that the class distilled when doing Experiment 2 into one sample and took the NMR of that one sample. a. Assign all the peaks to the protons in ethyl acetate b. Based on this spectrum would you say they sample is pure? Why or why not?
