Question

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. 

You are analyzing an essential oil extract from a flower using GC/MS and you
identify the terpene isomers linalool (MW 154) and eucalyptol (MW 154) in the products and
