What compound is consistent with the following ¹H NMR spectrum?

Question

Quizplus · Accepted Answer

Based on the given NMR spectrum, there are three distinct peaks present. The peak at around 2 ppm corresponds to the H on the carbonyl group (S1, P0), the peak at around 1 ppm corresponds to the H on the adjacent carbon (S1, P1), and the peak at around 0.8 ppm corresponds to the H on the two other carbons (S1, P11 and S1, P11). This pattern is consistent with a cyclobutanone, where there are three distinct types of H atoms on different carbons. Acetone and 2-butanone would have two distinct types of H atoms, while propanal would have four distinct types of H atoms.
