Problem: The following compounds all show a single line in their 1H NMR spectra. List them as they would appear in an NMR spectrum, e.g. by decreasing chemical shift with the lowest shift to the right. These compounds would appear in a spectrum in the order: (List compounds by letter with no commas.)

For this problem, we have to rank each molecule in decreasing value of chemical shift :


  • Recall that chemical shifts (at ppm) indicate the exact electrochemical environment that each proton is experiencing
  • In general, electronegative groups will pull electrons away from nuclei deshielding them
  • Shifts increase (move downfield) as protons become more deshielded. 1H NMR Chemical shifts table will appear as:
