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 (M+) 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:
– M+ peak = 78 m/z
– M+2 peak = 80 m/z
– base peak = 43 m/z
Which structure best fits the Ms data below?
