F. Fill in the following table identifying the peaks you labeled in your IR spectrum. Use Table 1 in Technique 15 of the lab manual to assign the peaks to the functional group vibrations listed. More than one peak (label) may appear for a "vibration" of a functional group (1 pt.) G. Draw the structure of ions responsible for the peaks at m/z=212,105 and 77 in mass spectrum of benzoin. (1 pt.)
