Chapter 9, Problem 44P

Deduce the structure of the compound that gives the following ¹H, ¹³C, and IR spectra (Figs. 9.54 –9.56 ). Assign all aspects of the ¹H and ¹³C spectra to the structure you propose. Use letters to correlate protons with the signals in the ¹H NMR spectrum, and numbers to correlate carbons with the signals in the ¹³C spectrum. The mass spectrum of this compound shows the molecular ion at m/z 148.
