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 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 cm. Both proton nmr and carbon-13...
