Problem: Select the compound that was used to generate the mass spectrum.a) 2-methylheptaneb) heptanec) 2,4-dimethylpentaned) hexane

FREE Expert Solution

We’re being asked to determine the compound that produces the given mass spectrum.


The following information can be acquired from the mass spectrum:

molecular ion peak: this gives us the approximate molecular weight of the compound. This is the peak with the largest m/z value.

base peak: this gives us the most stable fragment of the compound. This is the peak with the largest relative abundance.


From the given mass spectrum, we can see that:

– molecular ion peak = 100 m/z

– base peak = 43 m/z
