Benzene, toluene, and p-xylene (BTX) are often added to gasoline to boost octane ratings. What would be observed if a mixture of these three compounds were subjected to GC-MS analysis?

How many peaks would be present in the gas chtromatogram? What would be the relative order of the peaks? What molecular ions would be observed in the mass spectra?
