This reaction forms triphenylmethanol from benzophenone. How could you use infrared spectroscopy to show that the benzophenone had reacted (been consumed) and that the product of the reaction was triphenylmethanol

Complete Question

The complete question is shown on the first uploaded image  

The consumption of the reactant benzophenone and the production of  triphenylmethanol can be detected using their IR absorption spectrum

    This reaction is shown on the second uploaded image  

The reactant  benzophenone is a compound which contains a carbonyl functional group, and the stretching frequency of C=O bond has a high absorption at around and frequency band of this wavelength is absent in triphenylmethanol.

in the same vain the product   triphenylmethanol is a compound which contains a hydroxyl (OH) functional group, and the stretching frequency of O-H bond has a high absorption at around and frequency band of this wavelength is absent in benzophenone.

    To use infrared spectroscopy to show that the reaction is occurring is to show the disappearance of the  frequency band which indictes the consumption of benzophenone and the appearance    frequency band  which indictes the formation  of triphenylmethanol
