A three-carbon, nitrogen-containing compound exhibits 3 ¹³C NMR peaks (d 11.2, 27.3, and 44.9). Which of the following compounds best matches this spectral data? A) H₂NCH₂CH₂CH₂OH B) (CH₃)₂CHNH₂ C) CH₃NHCH₂CH₃ D) CH₃CH₂CH₂NH₂ E) CH₃CH₂C≡N

Question

Quizplus · Accepted Answer

The NMR peaks indicate that there are three different types of carbon environments in the molecule. The peak at d 44.9 indicates the presence of a carbon next to a nitrogen atom, which is consistent with the structure of choice D. The other peaks at d 27.3 and 11.2 are likely due to different types of carbon-hydrogen environments in the molecule. Choices A, B, C, and E do not have a nitrogen-bound carbon or have more than three carbons.
