Maen Cmambinatros Raba. DEPT 90: 128, 129, 132 ppm DEPT 45: 14, 23, 26, 38, 128, 129, 132ppm Decoupled: 14,23,26,38,128,129,132,137,200ppm Unknown 4 (23pts) MS data: (3pts-1pt per row) Provide a molecular formula that is consistent with the IR and NMR data and identify whether an isotopic cluster will be observed in the mass spectrum. Provide cationic structures for the molecular ion and all franmente with an intaneitu nf Ano, nr nraster IR data: (5pts-1pt/row) Provide complete information (i.e. all unique stretches and bends) for all functional groups in the structure. 'H NMR data: (6pts: 1pt/signal) Only label Hs that can be conclusively assigned with the available information. Draw a complete structure with all Hs explicitly shown. Signals should be labeled in order from lowest to highest chemical shift (i.e. label A= lowest chemical shift). 13 C NMR data: (9pts-1pt/signal) Only label Cs that can be conclusively assigned with the available information. Signals should be labeled in order from lowest to highest chemical shift (i.e. label A= lowest chemical shift)
