Which C₈H₁₀ compound gives the following ¹H NMR spectrum?

Question

Quizplus · Accepted Answer

Looking at the NMR spectrum, we can see that there are three peaks. The peak at around 2.2 ppm corresponds to the protons on the adjacent carbon to the sulfur (S1U1P11S1). Therefore, compound 1 is the only option that has this functional group. The other compounds either don't have a sulfur attached to a carbon with adjacent protons or have a different functional group, so they cannot give rise to the observed spectrum.
