Question

Hello im currently in organic chemistry. I am having trouble with spectroscopy questions:

  1. What m/z

value would you predict for the most stable fragment peak in the mass spectrum of 4-ethylheptane? a. 128 b. 127 c. 113 d. 99 e. 85

  • Which of the followng m/z values is the base peak for benzyl alcohol? a. 77 b. 108 c. 91 d. 17 e. 52
  • If you could show a detailed explaination that would be great, rather than just the answser. I have several other questions like these I need to answer. Initially I thought a graph was necessary to answer these questions. How do you answer without a graph? Thank you!
