a) Describe the difference between the base peak and the parent
ion (or molecular ion) peak.
b) Identify the base peak and the parent ion (or molecular ion)
peak (if any) according to the mass spectrum.
c) Identify the mass fragments which correspond to m/z = 77,
105, 111, and 139.
d) Identify and give explanations for the magnitude (or
intensity) of the peaks at m/z = 113, 141, and 218.
