Which of the following compounds corresponds to the ¹H NMR spectrum shown here?

Question

Quizplus · Accepted Answer

The NMR spectrum indicates the presence of four distinct proton environments, which corresponds to the four peaks in the spectrum. The chemical shifts and integrals of the peaks suggest the following:

- The peak at around 1 ppm with an integral of 3 corresponds to the methyl group (-CH3).
- The peak at around 2.2 ppm with an integral of 2 corresponds to the proton adjacent to the sulfur atom (-CH2-).
- The peak at around 3.3 ppm with an integral of 3 corresponds to the proton adjacent to the phosphorus atom (-CH2-).
- The peak at around 4.5 ppm with an integral of 1 corresponds to the proton attached to the oxygen atom (-OH).

Comparing the structures of the five choices, only choice C matches the above description of the NMR spectrum.
