Please give a through explanation
13. (16 pts) Compound P was a pleasant smelling, colorless liquid with a boiling point of 218 degrees C. It had no effect on either red or blue litmus paper. A mass spectrum of Compound P showed a molecular ion at 134 with a base peak at 105. When an ir spectrum was taken as a liquid film of Compound P, an intense peak was observed at 1683 em. Both proton nmr and carbon-13 nmr...

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...
