from the IR, 1H NMR spectrum and uv values decide what functional groups are present in the compound and deduce any other structural information you can, such as existance of conjugation in the carbonyl compound. for the UV spectrum values, use the woodward-fieser rules to help decide which structure is most consistent with both spectra.
Wavelength values for unknowns: 204nm and 222nm.
