Question

I would really appreciate the help. Have an entire worksheet with these graphs, and I'm not sure what to do. Please help :)
5. For each of the attached mass spectra, a. Find and label the molecular ion (M) peak and indicate its m/z value. Record this in your notebook. b. Find and label the base peak and indicate its m/z value. Record this in your notebook. c. Calculate the difference in mass (m/z) between the M peak and the base peak. What might be the structure of the radical fragment that was lost? Determine one or more plausible molecular formula(s) for each set of data and calculate the IHD for each From the molecular formula(s) you determined above, suggest one or more plausible structures for each. d. e.

Explanation / Answer

M+ is 46

base peak is 31

difference between M+ and base peak is 15 fragments may be CH3

31 may be CH3O

POSSIBLE STRUCTURE INCLUDES CH3OCH3
