Infrared (IR) spectroscopy is used to identify functional groups within a molecule. Which of these regions corresponds to the fingerprint region for the molecule below?
Explain how IR spectroscopy could be used to confirm product formation. Refer to specific functional groups, provide characteristic IR band frequencies and indicate the type of vibration (i.e.. stretching vs. bending). In this experiment, NaOH is used as a base, to convert 5-nitrobenzisoxazole to 2-hydroxy-5-nitrobenzonitrile.
What are the functional groups that would be on a molecule with the below IR spectroscopy? Agilent Resolutions Pro 100002 Name 2020-03-04T22-59-52
