Chapter 16, Problem 50P

Compounds Y and Z are isomers with the molecular formula $C_{10}{H}_{12}O$. The IR spectrum of each compound shows a strong absorption band near $1710c{m}^{-1}$. The ${}^{1}H$ NMR spectra of Y and Z are given in Figs. 16.4 and 16.5. Propose structures for Y and Z.

FIGURE 16.4 The ${}^{1}HNMR$ spectrum of compound Y, problem 16.50. expansions of the signals are shown in the offset plots.

FIGURE 16.5 the ${}^{1}HNMR$ spectrum of compound Z, problem 16.50. expansions of the signals are shown in the offset plots.
