help w/ unsaturation equations would be great too

Unknown 3 IR data 1H NMR data 13 C NMR data DEPT 135: positive: 126, 128, 128 ppm, negative: 33, 34, 44 ppm DEPT 90: 126, 128, 128 ppm DEPT 45: 33, 34, 44, 126, 128, 128ppm Decoupled: 33, 34, 44, 126, 128, 128, 141 ppm MS data Now that you've assembled a structure, complete the data tables below in the specified format. MS data: Provide cationic structures for the molecular ion and all fragments with an intensity of 40% or greater. IR data: Provide complete information (i.e. all unique stretches and bends) for all functional groups in the structure. 'H NMR data: Signals should be labeled in order from lowest to highest chemical shift (i.e. label A = lowest chemical shift). Draw a complete structure with all Hs explicitly shown. Only label Hs that can be conclusively assigned with the available information. Since HD is the overlap of signals from three sets of Hs, indicate the expected splitting for each set and the expected integration for each set in the box (i.e. list three spliting values and three integration values in row D). If HD can be labeled conclusively, label the Hss as HD1,HD2, and HD3, to distinguish which Hs are equivalent. 13 C. NMR data: Signals should be labeled in order from lowest to highest chemical shift (i.e. label A = lowest chemical shift). Only label Cs that can be conclusively assigned with the available information
