IR Spectroscopy of Aspirin 1. Draw the structure of aspirin and state the chemical name of aspirin. 2. Indicate the regions (circle and label on your IR spectrum) of your spectrum that correspond to a carbonyl and a hydroxyl functional group. Identify two other regions that correlate with other functional groups/structural features. Indicate these regions on your spectrum (circle and label on your IR spectrum). 3. Use your IR spectrum, melting point data, and FeCly test results to characterize the...
