4-h. CHUN | ppm H2N. NH NH2 NH2 (1 pts) Which structure (A-E) matches your deduced structure? Choose... CH120 ,-4 ppm OH A B C IT D E (1 pts) Which structure (A-E) matches your deduced structure? Choose. 41. CHgN2 The complex splitting patterns observed for the three signals from 6-7 ppm will be explained in NMR Workshop 2. For now, just note that there are three unique signals in this ppm range and pay attention to the DU calculation for this formula 7.0 6.5 pom Ppm NH2 & genero A B (1 pts) Which structure (A-E) matches your deduced structure? Choose (10pts) Question 4 Deduce the structure of each molecule below (4a-j) based on the provided NMR spectra. Note: Degree of unsaturation calculations are a valuable first step in this type of structure elucidation. Signals not integrated in the full spectrum (0-9+ ppm) are associated with solvent or other contaminants and can be ignored. 4-d. CgHyBro The complex splitting patterns observed for the three signals from 6.5-7.5 ppm will be explained in NMR Workshop 2. For now, just note that there are three unique signals in this ppm range and pay attention to the DU calculation for this formula 1.5 7. ppm 7 A ppm OH Br Br Br Br Br A B C D E (1 pts) Which structure (A-E) matches your deduced structure? Choose.. 4-g. C4H20 The complex splitting patterns observed for the three signals that each integrate for 1 proton will be explained in NMR Workshop 2. For now, just note their integrations and ppm ranges as well as pay attention to the DU calculation for this formula und 4.4 4.2 4.0 3.8 ppm 1 8 7 6 5 4 ppm HO A B D E (1 pts) Which structure (A-E) matches your deduced structure?
