Question

Assign specific C-13 and Proton signals to positions on the drawn structure. Assign each peak to its environment based off its chemical shift

Attach 1H and 13C NMR spectra of the coupling product. Draw your product below, and assign specific 13C and 1H signals from your spectra to their corresponding positions on the product. Which principles of Green Chemistry does this experiment illustrate? Explain how it illustrates each principle that you list.

Answer 1

Question: Assign specific C-13 and Proton signals to positions on the drawn structure. Assign each peak to its environment based off its chemical shift

Solution:

a.13 ppm (Hai 8.21 ppm) - CHL: 7.61 ppm) (No: "70ppm), 79.13 to the He lHQ = 3.95 ppm) 1.13 ppm) (H): 9.90 ppm) Hai-o-chih (methony) singlet HD : 8.90 ppm ( singlet) Hư: (7.61 ppm) doublet Ho : 8-21 ppm ( doublet) He : la H) doublet 19.13 ppm) Hy : 9.0 ppm (triplet) ) A peak at it is CD (l3 solvent peak. Ca : 51.83 ppm C6 : 160.92 ppm ç : 117. A7 ppm cd : 138. 36 ppm Ľ : 130. 69 ppm et : 157. As ppm Cg : 156.63 ppm (care same a environment) en : 117.7 ppm cs Scarched with 47.80 ppm Cams.carner'
