Question

A compound with molecular formula C7H160 displays the following IR and 'H-NMR spectra. The 13C NMR data suggest that there is some symmetry within the molecule. a) Calculate the degrees of unsaturation (DU) for the compound in the space provided below. DU = b) Identify and label the two indicated peaks in the IR spectrum in the boxes provided. Identify and label ALL peaks in the 'H NMR spectrum below. The numbers given on the 'H NMR are integration values for the number of hydrogens that are represented in each signal. c) Propose a structure for the compound that is consistent with the IR and NMR spectra in the box below. Structures written outside the box will NOT be graded.
