A compound has three signals in the ¹³C NMR spectrum and two signals in the ¹H-NMR spectrum. Which is most likely the compound?

Question

Quizplus · Accepted Answer

Ortho dibromobenzene has a symmetrical structure that would result in three distinct environments for the carbon atoms, as observed in the ^13C NMR spectrum. Additionally, the proximity of the hydrogen atoms in the ortho position leads to them being in similar environments, resulting in two signals in the ^1H-NMR spectrum.
