Please identify the main functional groups in the IR spectra of two different molecules. I can't figure out what the peaks in these IR signify. I don't understand what the peak in the 3400 cm area of the second IR is. 95 85 C(CH3)3 80 C(CH3)3 N OH 75- 'N OH C(CH3)3 70- C(CH3)3 65 60 4000 3750 3500 3250 3000 2750 2500 2250 2000 1750 1500 1250 1/cm 95 C(CH3)3 85 C(CHa)3 N C Mn Cl 80 75 70...

please help me finish all the questions on the first picture, be sure to use the IR scans I uploaded below and please label all the functional group showed on the two IR scans. Thanks. Exp. 11 Synthesis and Analysis of Aspirin 2. What functional group is created during the synthesis process that is found in aspirin, but not in salicylic acid? Draw aspirin structure and circle the group(s). 3. Consider both the IR scans of salicylic acid and aspirin....
