(a) Interpretation: Two molecular formulas for the given molecules are to be proposed. Concept introduction: Molecular mass is the sum of the atomic weights of each constituent element multiplied by the number of atoms of that element. The compound that contain C, H and O atoms always have a molecular ion with even mass.
