Halogenated compounds are particularly easy to identify by their mass spectra because chlorine and bromine occur naturally as mixtures of two abundant isotopes. Chlorine occurs as 35Cl (75.8%) and 37Cl (24.2%); bromine occurs as 79Br (50.7%) and 81Br (49.3%). For the compound Chlorocyclohexane, C6H11Cl: At what masses do the molecular ions occur? (List in order of increasing mass separated by commas, e. g. 120,122.) What are the percentages of each molecular ion? (List to nearest 1% in order of increasing mass separated by commas, e. g. 55,45.
