Practice Final 1. Answer the following questions about mass spectrometry and be prepared to draw what is required. a. You have a mass spec with peaks at the following m/z: 108 & 106, 93, 91, 79, 77 and 71. Circle the chloropentane isomer that corresponds with this. CI ما Draw the fragment that corresponds to the 77 peak. Ха b. You have a mass spec with peaks at the following m/z: 70 and 31. The molecular ion peaks at 88 tends not to show up. Circle the isomer of pentyl alcohol that corresponds with this. OH OH Draw the fragment that corresponds to the 70 peak. OH c. Given the molecular ion of the ketone below, what are the 4 major peaks you would see in its mass spec? Also, draw the mechanism for the formation of any of the fragment ion peaks you list. 1 2 3 4 m/z
