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...
