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

Question

Quizplus · Accepted Answer

The ¹H NMR spectrum shows 2 peaks, indicating the presence of 2 different types of hydrogen atoms. The peak at 1.5 ppm corresponds to the hydrogen atoms on the cyclobutanone ring, while the peak at 2.5 ppm corresponds to the hydrogen atoms on the keto group. Acetone, Propanal, and 2-butanone all have only one type of hydrogen atom, so they would not show 2 peaks on the NMR spectrum. Cyclobutanone has both a cycloalkane ring and a keto group, which is consistent with the observed peaks.
