a. Write the name and chemical formula of the alkyl group that was lost from the molecular ion to give the species that is circled on the following spectrum:
b. Comparing âmethylâ âethylâ to âtert-butylâ, which is more a more likely fragment to be seen in mass spectrometry (or are they both approximately equally likely)? For example, assuming 2,2-dimethylbutane were to fragment at the C2âC3 bond, which of the two fragments would give a greater signal? Briefly explain why.
c. Which one of the following four molecules is the one whose mass spectrum is given below?
