Grignard reaction was conducted using bromobenzene and benzaldehyde to make diphenylmethanol. How can we know that the IR spectra for diphenylmethanol is in fact diphenylmethanol apart from the title, keeping in mind the spectra of the reactants? Mention specific wavenumber and their corresponding functional groups.
