7. (3 pts.) Shown below is the 'HNMR spectrum of curcumin in solution. In solution, curcumin could exist in diketone form or enol form, or as a mixture of the two. We can determine if the spectrum corresponds to the keto form or the enol form or a mixture of the two forms. If the spectrum corresponds to both the keto and enol form we should see the peaks for Ha protons in the keto form and the Hb proton...
