Question

A and B are isomeric dicarbonyl compounds of the molecular formula C5H8O2. The 1H NMR spectrum of A contains a singlet at 2.05 ppm and another singlet at 5.40 ppm. The 1H NMR spectrum of B contains three signals: a singlet at 2.3 ppm, a triplet at 1.10 ppm and a quartet at 2.70 ppm. Suggest structures for A and B and draw them in their respective boxes below.

Step 1

Both \( A \) and \( B \) have the formula \( \mathrm{C}_{5} \mathrm{H}_{8} \mathrm{O}_{2} \) and are isomeric dicarbonyl compounds, meaning they each contain two carbonyl groups. Show more…
