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%);

Boron compounds also stand out owing to the two isotopes ¹⁰B (19.9%) and ¹¹B (80.1%).

For the compound Bromomethane, CH₃Br:

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.)
