13. (16 pts) Compound P was a white crystalline solid with a melting point of 180-181 degrees C. It had very little solubility in water, but the water solution turned blue litmus paper red. Mass, infrared, carbon-13 nmr, and proton nmr spectra were taken of Compound P and are shown on the following pages. The multiplicities for the C-13 spectrum, apparently taken in another experiment, are...
