For the given compounds, number of signals in 13 C NMR spectrum should be found Concept introduction: The carbon atoms of aromatic rings typically produce signals in the range of 100-150ppm in 13 C NMR spectrum. The number of signals is very helpful in determining the specific substitution for substituted aromatic ring. The 13 C NMR spectrum gives information on the different electronic environments of carbon. As like 1 H NMR , the number of signals generated in 13 C NMR are predicted by performing symmetry operations (rotation or reflection symmetry). Only chemical shift values are reported in the spectrum but not the multiplicity and integration values because the coupling between two neighboring 13 C − 13 C nuclei are weakly involved due to the low abundance of 13 C isotopes of carbon atom.
