Answer: C.1,3-dibromo benzene
Bromine has two isotopes: 51% 79Br and 49% 81Br. As both are having almost close percentage abundance both molecular ions will have almost the same intensity along with third molecular ion peak with double intensity in between them.
Molecular ions of isotopes = 79Br+ , 81Br+
Possible combination molecular ion peaks: [79Br79Br]+ , [81Br81Br]+ , [79Br81Br]+
Both [79Br79Br]+ and [81Br81Br]+ will have same intensity, [79Br81Br]+ will have double to other two.

Name: 2.2 Hydrogen The relative isotopic abundance for hydrogen 2H: 1H is about 0.00016: 1, and therefore hydrogen isotopic substitutions are unlikely to play a major role in any observed (M+1) peak. The isotope 2H is called "heavy hydrogen or deuterium, and is given the symbol D. We can often provide support for mechanisms by incorporating isotopes such as 13C or D into compounds using isotopically labelled reagents. Mass spectrometry is a useful tool for analyzing such isotopic incorporation by...
