Challenge Problems
Push your limits with advanced challenges
You have an unknown compound in a solvent. After conducting NMR, you find two peaks: one at 2.5 ppm (integral = 1.0) and another at 7.6 ppm (integral = 4.0) for the standard. Given the internal standard's concentration is known, calculate the unknown's concentration.
💡 Hint: Think about how you can relate the moles from the internal standard to the unknown based on their peak areas.
Discuss potential discrepancies when analyzing mixtures compared to pure compounds in quantitative NMR spectroscopy. How might these affect results?
💡 Hint: Reflect on how mixtures behave differently than individual substances.
