QUESTION:

For each NMR spectrum, propose a structure consistent with the spectrum and the additional information provided.
(a) Elemental analysis shows the molecular formula to be \(\mathrm{C}_{8} \mathrm{H}_{7} \mathrm{OCI}\). The IR spectrum shows a moderate absorption at \(1602 \mathrm{~cm}^{-1}\) and a strong absorption at \(1690 \mathrm{~cm}^{-1}\)

(b) The mass spectrum shows a double molecular ion of ratio 1:1 at m/z 184 and 186.
