Assume you are carrying out the conversion of 1-bromobutane to 1-butanol. How could you use IR spectroscopy to determine when the reaction is complete? As the reaction progress the 3400-3640 cm^-¹IR band should increase in intensity.

Question

Quizplus · Accepted Answer

The 3400 cm-1 IR band corresponds to the -OH stretch in alcohols. As the reaction progresses and 1-bromobutane is converted to 1-butanol, the intensity of this band should increase due to the formation of more alcohol product. Therefore, monitoring the increase in intensity of the 3400 cm-1 band using IR spectroscopy can be used to determine when the reaction is complete.
