"WebThirdly, on the hydrobenzoin spectra, there is a medium band around 2980 1/cm, while benzoin has a small/weak band in the same location. What is this showing? It this because hydrobenzoin has 1 more C-H bond than benzoin? Or is it something else entirely? Lastly, why is it that for both IR spectra, the band in the -OH region has two peaks?
