Pre-lab 6: Lab- NMR assignments Name:_____________________

Draw the expanded molecular structure if necessary and assign the Proton NMR frequencies in the following Spectra: ( use correlation charts or peaks values given at the end of the assignment).

1) Nitropropane(10 pts) Proton NMR

2)

2) 3-methyl-1-butene (10 pts) Proton NMR

3) ethyl acetate (10 pts) Proton NMR

Draw the expanded molecular structure if necessary and assign the decoupled Carbon-13 NMR frequencies in the following Spectra: ( use correlation charts or peaks values given at the end of the assignment). What peaks will show more structure in the coupled Carbon-13 NMR? What are their multiplicities (doublet, triplet, quartet etc.)

4) Cyclohexanone (10 pts) ¹³C NMR decoupled

5) 4-methyl-2-pentanone(10 pts) ¹³C NMR decoupled
