please help on as much as possible!! i really need help!!

2. (6 points) Provide your work and eventually a reasonable structure for the three spectra provided (one just listed at the bottom of this page and two attached on the following pages, labeled AS "a" and "b"). Note that a complete answer:starts by labeling each signal in the spectrum ("a". "b", "c". etc) . then analyzes each signal individually . then connecting some signals to give fragments using the splitting checks the H/C counts in the fragments vs the molecular formula checks the degrees of unsaturation accounted for in the fragments vs that calculated from the molecular formula and only then assembles the structure, with labels on all the hydrogens in your final structure. You MUST show your work for full credit just providing a structure without any indications of how you arrived at it will get 12 pt at the most, even if it is the correct structure. Please feel free to attach as many additional pages with your work on it as you wish. Note that for the first spectrum, it is all on one page, with "zooms (magnified versions) of the signals above the whole spectrum. The integration values are given below the signals. For the second spectrum, it is two pages, with the "zooms" on the 2nd page. Integration values are below the signals on the full spectrum (first page).
