Question 1
A mass spectrometer provides a spectrum with a molecular ion peak at 200 m/z followed by a base peak at 100 m/z. Assuming the base peak represents a common fragment, what might this suggest about the molecular structure?
💡 Hint: Think about how structure influences fragment stability.
Question 2
If a mass spectrum shows an M+2 peak at one-third the height of the M+ peak, what element might be suspected in the compound?
💡 Hint: Recall the ratio of isotopes for common halogens.
