Unformatted text preview: 5. Give the m/z values of two major fragments you would expect to see in the mass spectrum of the following compound. Mark the one that is most likely to show up as the base peak, and explain. OH m/z = m/z = 6. What two circumstances lead to fragments with even m/z values? 7. Give three important pieces of information about the molecular formula of the compound (other than the molecular weight) that you can obtain from this mass spec data. m/z Relative abundance 34 21 52 35 91 100 102 22 111 (M + ) 10 113 3.3...
