Concept

Problem: How many kinds of chemically non-equivalent hydrogens are there in each of the following compounds?a) Tylenol (analgesic and antipyretic) b)

FREE Expert Solution

For this problem, we need to determine how many kinds of chemically non-equivalent Hs in each of the ff. compounds

  • Recall that for 1H-NMR analysis, there are as many signals on each spectrum as there are unique, non-equivalent protons
  • In this case, let's assume that Hs bound to the same C is equivalent 
  • Take note that symmetry will reduce the total number of signals
