An unknown oxygen-containing organic molecule shows a parent peak on its mass spectra at m/z 122. With no information from the visible or uv, the IR revealed major broad absorptions from 2500 cm1 to 3500 cm1, and strong sharp absorptions at 2930 cm-1, 1690 cm1, and 1230 cm1. The 1H NMR revealed a singlet downfield around d 13 (1H) and a multiplet at d 7.2 (5H). The molecule consistent with these facts is:
