The following two compounds are isomeric esters derived from acetic acid, each with formula C5H10O2. These expanded spectra clearly show the splitting patterns: singlet, doublet, triplet, quartet, etc. Integral curves are drawn on the spectra, along with relative integration values provided just above the scale and under each set of peaks. These numbers indicate the number of protons assigned to each pattern. Remember that these integral values are approximate. You will need to round the values off to the nearest whole number. Draw the structure of each compound.
