2.Consult the IR spectrum of 4-methoxyphenol included below, on page 6. For each of the following functional group vibrations, list a specific (do NOT report a general range) absorption band in the IR spectrum. Report the frequencies in cm-1 (the units of the x-axis of the IR spectrum). The specific absorbance band frequency values are listed below each band. a) Alcohol O-H stretch b) Arene (phenyl or aromatic) C-H stretch c) Alkane C-H stretch
