What is the structure of the compound in the following ¹H-NMR spectrum with the molecular formula C₄H₇Br? Relative integration is shown.

Question

Quizplus · Accepted Answer

The ¹H-NMR spectrum shows 4 signals with relative integrations of 2:3:2:3. This means that there are two sets of protons that are chemically equivalent and another two sets that are also chemically equivalent. The most likely structure that fits this pattern is a symmetrical molecule with two different substituents. Looking at the molecular formula, we see that there are two bromine atoms and two sulfur atoms, which suggests a molecule with two phenyl rings as substituents. The only answer choice that fits this pattern is (C).
