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.

Q1:

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

  • A C H 3
  • B C H C H 3 2
  • C M o r e i n f o r m a t i o n i s n e e d e d .
  • D C O O H

Q2:

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

Q3:

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
