Challenge Problems
Push your limits with challenges.
Question 1
A mass spectrum shows M$^+$ at m/z 98 and an M+1 peak at 8% of M$^+$. Estimate the number of carbon atoms in the compound.
💡 Hint: Recall the calculations for estimating carbon from isotope peaks.
Question 2
If a compound shows a prominent M$^+$ at 100 m/z, a base peak at 50 m/z, and fragment ions at 70 m/z and 40 m/z, discuss the possible structure based on the fragment ions.
💡 Hint: Consider how bonds might break to form those fragments.
