The following two ester structures have the same molecular formula.

The spectra for these compounds are shown below.

Write the structure of each ester next to its nmr spectrum

On the structure, label the sets of equivalent hydrogens as a, b, c, etc.

On the spectrum, label the signals with the letter (a, b, c, etc.) of the set of equivalent hydrogens.

Give a short explanation of how you selected the correct spectrum for each structure
