Worksheet: Functional Groups in NMR Spectra

In this worksheet, we will practice identifying functional groups in NMR spectra based on the chemical shifts and splitting patterns of signals.


The 1H NMR spectrum of propanoic acid exhibits three peaks. Which group corresponds to the most downfield peak?

  • ACH3
  • BCHCH32
  • CMore information is needed.


The 1H NMR spectrum of acetone exhibits a singlet. In which range of chemical shifts would you expect to find this singlet?

  • A3.5–5.0 ppm
  • B1.5–2.5 ppm
  • C0.0–0.5 ppm
  • D0.5–1.5 ppm
  • E2.5–3.5 ppm


What structural information does 1H-NMR spectroscopy not provide?

  • AThe number of different types of hydrogens in a molecule
  • BThe electronic environment of different types of hydrogens
  • CThe relative numbers of different types of hydrogens
  • DThe relative abundance of different isotopes of hydrogen
