IR spectroscopy can be used to analyze the structure of various organic compounds. If you were to compare the IR spectra for 4-aminophenol and acetaminophen, what would the major differences be between the two? List two main differences. In your answer, refer to appropriate stretching frequencies and give approximate (ranges) for expected peaks. (You should refer to the IR section in your text book for relevant data).
