Challenge Problems
Push your limits with challenges.
Question 1
You have a compound with a mass spectrum showing an M⁺ peak at 58 m/z and a base peak at 29 m/z. Identify possible functional groups present in the compound.
💡 Hint: Look closely at common fragment patterns when analyzing the m/z ratios.
Question 2
Explain how you would estimate the number of carbon atoms in a compound using the ratio of the M⁺ and M+1 peaks.
💡 Hint: Think about how the presence of 13C isotopes influences the M+1 peak's intensity.
