Which of the following statements about ¹³C NMR is not true? A)"In ¹³C proton-decoupled NMR spectra,all peaks are singlets." B)"¹³C NMR spectra display peaks for only carbons that bear hydrogen atoms." C)"¹³C NMR chemical shifts occur over a greater range than ¹H NMR chemical shifts." D)"¹³C NMR easily differentiates between the different hybridized carbons (sp³,sp²,and sp hybridized carbons)."

Question

¹³C NMR (which seems to be a placeholder for ^13C NMR) spectra display peaks for all carbons in a molecule, not just those that bear hydrogen atoms. This is in contrast to proton (^1H) NMR, which only shows signals for hydrogen atoms.
