**Question:**How many signals are expected in the decoupled \(^{13}C\) NMR spectrum of 3-bromotoluene?**Diagram Explanation:**The diagram shows the molecular structure of 3-bromotoluene. It is a benzene ring substituted with a bromine (Br) atom and a methyl (CH\(_3\)) group.- **Benzene Ring**: The benzene ring in the structure exhibits a regular hexagon of alternating double bonds.- **Substituents**: - The bromine atom is attached to the third carbon of the ring. - The methyl group (CH\(_3\)) is attached to the carbon at the opposite position in the benzene ring of the bromine atom.In \(^{13}C\) NMR spectroscopy, each unique carbon environment gives rise to a separate signal. The molecule 3-bromotoluene has unique carbon environments due to the bromine and methyl substituents affecting the symmetry of the benzene ring. Therefore, the number of expected \(^{13}C\) NMR signals equals the number of distinct carbon environments in this structure.

Concept explainers

NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

8. Sketch the off-resonance-decoupled 1³C spectra of the following compound. H H C C-H H The splitting pattern of off-resonance decoupled spectrum indicates the number of protons attached to the carbon. 13C nuclei are split only by the protons attached directly to them. The N + 1 rule applies: a carbon with N number of protons gives a signal with N + 1 peaks (e.g. carbon atom with one proton appears as a doublet; carbon with two attached protons gives a triplet etc.) • Carbon atoms with more hydrogens absorb more strongly.
