a) Identify the unknown from its 70 eV EI mass spectrum.
Follow the guidelines in Chap. 6.16.
You should first have identified the isotopic pattern of the molecular ion as that of Br3 and a very low number of carbons. Having understood the isotpic pattern, one locates the monoisotopic peak at m/z 250. Subtraction of a Br radical (79 u) brings us to m/z 171 …
