Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider an unidentified organic compound that shows a strong O-H stretching band in its IR spectrum and is suspected to contain a carbonyl group based on another observed peak. Discuss how you would approach structural elucidation given these IR data.

💡 Hint: Combine methods to get the full picture.

Challenge 2 Hard

If an organic compound displays broad peaks in theIR spectrum above and below 3000 cm^-1 in addition to a strong carbonyl peak, what further steps should be taken for analysis?

💡 Hint: Think beyond IR for full structural clues.
