Question

The chemical reaction shown below converts an alcohol into a ketone. Explain (in words) how you would use Infrared spectroscopy to determine if all of the alcohol had reacted and that a ketone was the product of the reaction.

In your explanation you need to specify the shape and frequency of the infrared absorption peak that goes away when the alcohol reacts and what functional group it represents, and the shape and frequency of the infrared absorption peak that grows in as the reaction progresses, and what functional group it represents.

Explanation / Answer

When alcohol is irradiated with infrared light th th alcohol absorbs th light corresponding to th particular wavenumber and we get a peak at 3200 - 3640 cm^-1 is the spectroscopy. But when the alcohol starts converting into ketone then the peak starts shifting towards 1660 - 1760 cm^-1 . Since CO bond is highly polar we get a large peak at 1660 - 1760 cm^-1 which shows us that all th alcohol has been convertd into ketone.
