The following is intended for students who have already covered IR spectroscopy (Chapter 14). Consider the figure shown in Problem 7.91: Ph Ph ROH -Br Ph- -OR Ph Ph Ph 2 Ph = 3- 2a: R = H 2b: R= CH3 2c: R = CH2CH3 1 IR spectroscopy is an ideal tool for monitoring the conversion of 1 to 2a, while other forms of spectroscopy will be better suited for monitoring the conversion of 1 to 2b or 1 to 2c. Select the reasons why IR is an ideal tool ONLY for conversion of 1 to 2a. Because the O-H absorbance is in the fingerprint region, it is the best way to identify the product. O The CH3 group absorbs only in the fingerprint region so it is hard to identify. O An OH absorbance is diagnostically useful but C-Br and C-O absorbances are in the fingerprint region. C-Br and C-O absorbances are diagnostically useful but the O-H absorbance is in the fingerprint region.
