Identify how IR spectroscopy might be used to monitor the progress of the following reaction. A. The reactant should not have signals at 1650 cm1 or 3100 cm1, while the product(s) should have such signals. B. The reactant should have a broad signal from 3200 3600 cm-1, while the product(s) should lack this signal and instead should have a signal at ~1720 cm1.C. The reactant should have signals at 1650 cm-and 3100 cm-1, while the product(s) should not have either of these signals. D. The reactant should have signals at 1650 cm-1 and 3100 cm-1, while the product(s) should both have a signal at ~1720 cm-1.
