Draw the structure that would be responsible for the spectrum. To make interpretation a little easier, I have included the splitting type and number of hydrogens for each set of signals in the spectrum, from left to right. In other words, C4H8O; quartet (2H), triplet (3H), singlet (3H) means, that the three sets of peaks, starting from the left are a quartet due to two hydrogens, a triplet due to three hydrogens and a singlet due to three hydrogens. CsHIoO2,...
