These compounds are: MW 86u: 2,3 butanedione (diacetyl), C4H6O2; allyl ethyl ether, C5H10O, cyclopropane carboxylic acid, C4H6O2: γ-butyrolactone, C4H6O2. MW 88u: 3-hydroxybutanone (acetoin), C4H8O2; n-butyric acid, C4H8O2; ethyl acetate, C4H8O2; pyruvic acid, C3H4O3. All 24 reactions proceed at the gas kinetic rate, the dominant primary product ions of the H3O+ reactions being the protonated reactant molecules, MH+ with a common mass-to-charge ratio, m/z, in each group of isobaric compounds;...
