Practice Problem

1H NMR spectrum of unknown C10H12O2 with integration trace; peaks near 8, 7, 3.9, 2.6, 1.2 ppm and TMS at 0

The 1Hnmr spectrum of the unknown C10H12O2 compound is shown above. Seven structural formulas of some possible candidates for this compound are presented below. After reviewing the chemical shifts, coupling patterns and integration values shown in this spectrum, select the structure most likely to give this spectrum, and enter the corresponding letter ( A through G ) in the answer box.
Do not enter punctuation (eg. commas or semicolons) or spaces.

Seven candidate C10H12O2 structures A-G: aromatic esters and ketones (ethyl/methyl toluate, ethoxy/methoxy acetophenones, propiophenone, cresyl esters)
Which structure best fits the above 1Hnmr spectrum .....
