Question

Please help to explain how I can figure out this. I have attached photos that pertain to the questions.

C6H12O2

6. How many unique types of carbons are present in the molecule?

7. For each unique carbon, list the chemical shift and possible hybridization.

Unknown C312 200 180 160 140 120 100 80 60 40 20 0 ppm 6 resonances

Answer 1

at 694 POST 19.f, E Cc Higg DBE 2042 - H 206012-12 - 1. 6 Be NMR spectra shows 6 discrete signals. That indicates 6 unique types of c in the molecules! ☺ IR- streching at 5 = 1750 cm' confirms the presence of an ester functional group ① mass spectra shows base peak at 43 which indicates the on Cha=0 resulted from &- fragmentation of the following comperend. 13 C NMR Chemical shift malces along with hybridisation are assigned in the structure - 2 (40%) 0 30 0 66 21 CM Ceph ) , 20 CHg 13 (sps) 170
