Is there a carbonyl in your unknown? State how you know. If one is present, state how the frequency narrows down the functional group it is a part of (carboxylic acid, ketone, aldehyde, ester, amide). 2. What functional groups are present in your unknown molecule? For each, correlate the functional group with the frequency of the identifying peak.

3.What peaks would expect to find for you Vs, cie'thy) amine thy) in the InfraRed' spectrum? +-butyl 'amine us. n-butyl amine

Instructions: Draw the structure of the each compound next to its matching spectrum. Mark peaks on the spectra that helped you pick that compound. -CEN COH OH OH `NH, HO,

2) On spectra 2 are the mass, IR and 13 C and 1 H NMRspectra of an organic compound.a) From these spectra, determine the structure of the molecule. Rememberto ignore the triad in the 13 C NMR spectrum at 7 ppm that comes from theNMR solvent. b) Draw the structure of the molecule and label each hydrogen with a letter(A, B, C...). Then fill in the peak assignment table below.  hydrogen chemical shift integration splitting pattern couples to
