What is the size (in amu) of the neutral fragment that was lost to give the ion responsible for the base peak at m/z = 43?
a. What combination of atoms weighs the amount you reported above, and whose loss could account for the peak at m/z = 43?
b. Construct an explanation for why the peak at m/z = 43 is called the [M-15]+ peak.
c. Using the same naming strategy, name the peak on the mass spectrum at m/z = 15.
