1. Simulated data for a compound with formula C13H11O3 is shown below. Note the broad singlet at 7.58ppm does not show coupling to adjacent H's. The IR has notable peaks at 3413,1714cm1 amongst others. The 13C, DEPT-135, and DEPT-90 are tabulated below. Propose a structure and assign as much as you can (including diastereotopic H's if present). Expansions of various regions are chniwn an the navt name 1.
