What is the most likely m/z value for the base peak in the mass spectrum of 3-methylpentane?
The base peak in the mass spectrum of benzyl bromide (PhCH2Br) has a m/z of 91. Draw the structure of this fragment ion.
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.
