Questions and Answers

Which type of protons are associated with distinct signals in NMR?

  • Chiral protons
  • Diastereotopic protons (correct)
  • Test group protons
  • Enantiotopic protons

What happens when diastereotopic protons are replaced with a test group?

  • They have equal chemical shifts
  • They become chemically distinct in reactions with chiral molecules
  • They become enantiotopic protons
  • They give rise to diastereomers (correct)
