Challenge Problems
Push your limits with challenges.
Question 1
Given a mass spectrum with peaks at m/z 72 (M$^+$), 57 (base peak), and 43, with significant M+1 and M+2 peaks, deduce the likely molecular formula and discuss possible structural units present.
💡 Hint: Analyze the peak at m/z 57 carefully; it may provide clues.
Question 2
A compound with a molecular ion peak at m/z 98 shows fragment ions at m/z 81, 69, and 43. Discuss how you would approach determining its possible structure.
💡 Hint: Consider common fragmentation patterns for carbon-based compounds.
