< ne following and "U NMK specura were taken on an unknown compouna with the molecular formula САНО, Integration 2 2 3 3 - T 10 9 11 8 7 6 5 4 3 2 0 ppm 140 80 60 40 20 160 200 180 120 100 Ppm Perform a HDI analysis of the formula to indicate how many degrees of unsaturation are present. ii) There are four signals in the 'H NMR (8.0, 7.0, 4.0, 2.5 ppm) in a ratio of 2:23:3. What are the multiplicities (peak splitting) for each peak and how many adjacent protons does this indicate for each peak 101) The 13C NMR shows one signal at 195, four between 100-170, one at 60 and one at 30. Propose partial structures that match this data iv) From these spectra predict from the four compounds below which is the unknown. Circle the structure you feel best matches the data CH, CH HEC H₃CO HEC HO с A B D E
