PART 3 For each set of data on pages 5-9, calculate and record the degree of unsaturation. Then use your problem solving skills to determine the chemical structure that is consistent with ALL of the data on each page. You are not required to label the spectra (but feel free to do so). This entire assignment is to be completed independently Suggestion for a general method to determine a chemical structure based on the provided molecular formula, IR, H-NMR and...

PLEASE EXPLAIN IT IN DETAIL THANK YOU
Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...
