The ¹H NMR spectrum of which of the compounds below,all of formula C₇H₁₂O₂,would consist of a singlet,a doublet and a triplet only?

Question

Quizplus · Accepted Answer

The singlet in the NMR spectrum corresponds to the methyl group attached to the oxygen atom (S1S1P0H group), the doublet corresponds to the two equivalent protons on the cyclohexyl ring (S1B112S1U1B0 group), and the triplet corresponds to the three equivalent protons on the methyl group attached to the nitrogen atom (S1B0NS1U1B12S1U1B0 group). Only compound IV has all of these groups, so its NMR spectrum would consist of a singlet, a doublet, and a triplet only.
