Please label and interpret the following IR spectra of an unknown compound. Label each important absorption on the spectrum with a structural feature of your unknown and identify the unknown compound.
Homework Answers
First of all we can't predict comolcom structure by IR, we can only predict major functional groups.
Peak at 3450 cm-1 is due to OH stretch and at 2985 is due to CH stretch and at 1740 for ester carbCarb group stretch, C=O. And at 1220 is for C-O stretches.
Hence compComp may be hydroxy ester.
