Mass Spectrometry Problems Directions: Show all work for this problem. You may want to write your answers on a piece of notebook paper. Assign a structure that would be expected to give rise to each of the following mass spectra. Note: Some of these problems may have more than one reasonable answer. In some cases, infrared spectral data have been included in order to make the solution to the problems more reasonable. You will need to use the Rule of Thirteen and the Index of Hydrogen Deficiency to do these problems.
