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 C8H7OCl. The IR spectrum shows a moderate absorption at 1602 cm-1 and a strong absorption at 1690 cm-1.

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