Chapter 19.8D, Problem 19.10P
- a. Show how fragmentation occurs to give the base peak at m/z 58 in the mass spectrum of ethyl propyl
amine (N-ethylpropan-1-amine), shown below. - b. Show how a similar cleavage in the ethyl group gives an ion of m/z 72.
- c. Explain why the peak at m/z 72 is much weaker than the one at m/z 58.

Although 2,2-dimethylhexane has a molecular weight of 114, no peak is observed at m/z = 114. The base peak in the mass spectrum occurs at M-57
(a) Draw the fragmentation responsible for the formation of M-57 ion
(b) Explain why this cation is the most abundant ion to pass through the spectrometer.
(c) Explain why no molecular ion survive long enough to be detected.
(d) Can you offer an explanation as to why M-15 peak is not the base peak?
On each mass spectrum above, indicate the base peak and the molecular ion peak (or at least where you would expect to find it) and if the base peak on the mass spectrum for linalool has m/z 71, propose a structure for this fragment ion.
The base peak in the mass spectrum of hexanamide appears at m/z = 59. Draw the ion that corresponds to this mass peak, and show how it is produced from the molecular ion.
