What molecular ions will be present in a mass spectrum of 2-chloropropane,(CH3)2CHCl ?
4. 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 "CI (75.8%)
and "CI (24.2%). Ignore the presence of "C isotopes.
For the compound, C,H,Cl;:
a) At what masses do the molecular ions occur?
b)What are the percentages of cach molecular ion?
Using the rule of 13, what is a possible formula for M=113 (100%) on a mass spectrum?
all of the above are possible molecular formulas
CH130
CH15N
