Challenge Problems
Push your limits with challenges.
Question 1
An organic compound shows three distinct NMR peaks at 1.2, 2.3, and 7.5 ppm. If the integration of these peaks gives 3:2:1 ratios, calculate the corresponding number of protons for each peak.
💡 Hint: Consider the relative positions and environments of the protons.
Question 2
If an NMR spectrum yields a peak for 6 equivalent protons at 0.9 ppm and a neighboring peak for 3 protons at 1.2 ppm with splitting, what does this imply about the molecular structure?
💡 Hint: Evaluate the relationship of equivalent protons and their neighbors using the 'n + 1' rule.
