Assume you are carrying out the conversion of 1-bromobutane to butan-1-ol. How could you use IR spectroscopy to determine when the reaction is complete?

Question

Quizplus · Accepted Answer

The Answer is The infrared spectrum of the starting bromide contains only alkyl C-H absorptions which appear in the 2850-2960 cm^-sup>1 region. As the reaction progresses, a broad absorption at 3400-3640 cm^-¹, due to the O-H stretch, should develop. When the relative intensity of this band no longer increases, the reaction is complete.
