What are the functional groups of each IR spectra and why?
Homework Answers
1. Peaks at 2985 and 1700 are due to CH stretch and C=O stretch. So compound may have ketone functional group.
2. Peak at 3450 is due to OH and at 3080 for =CH stretch and at weakpeak at 1600 for C=C and a weak peak at 1050 for C-O stretches. so it may have phenol functional group.
3. Peaks at 2975 and 1745 are due to CH and C=O stretch and a strong peak at 1200 corresponds to C-O stretch. So if may have an ester functional group.
