Question

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 35C1 (75.8%) and 37C1 (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 Bromoethane, C,H;Br: For the compound Bromoethane, C,HsBr At what masses do the molecular ions occur? 08.110 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) Submit Answer Try Another Version 2 item attempts remaining

Explanation / Answer

M+ ion peak at 108 g.

M+ + 2 ion peak at 110 g.

% M+ : M+ + 2 = 50.5 : 49.5
