The given compounds to be distinguished using both 13 C NMR and 1 H NMR spectroscopy. Concept Introduction : Both 13 C NMR and 1 H NMR spectroscopy gives information on the different electronic environments of carbon and protons respectively. 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.
