Challenge Problems

Push your limits with challenges.

Question 1

Given an IR spectrum showing strong peaks at 3300 cm^-1 (broad) and 1740 cm^-1, identify possible functional groups present and justify your reasoning.

💡 Hint: Focus on interpreting the peaks in relation to known functional group absorptions.

Question 2

Analyze an IR spectrum where no prominent peaks are observed above 1500 cm^-1. Discuss possible molecular structures that could lead to this lack of absorption.

💡 Hint: Think about polarity and bond characteristics.
