These spectra are from the set of seven compounds from the pre-lab for this experiment: acetanilide, acetic anhydride, acetone, benzoic acid, caffeine, ethyl-4-aminobenzoate, and ethyl acetate. For each spectrum list the wavenumber of any carbonyl (C=O) stretch present and identify the molecule. Give a brief (one sentence) explanation for your choice. One compound will not be used.

Please help ASAP thank you only correct answers
