How many different 13CNMR signals are produced by the following molecules?

what would the chemical shift be for each proton in this molecule, and how did you come up with that number for each chemical shift?

How many 13CNMR signals are produced by each of the following molecules?

The picture of the question is attached

Assign the correct constitutional isomer to this spectrum (C5H12O)

how many peaks wouldyou expect to see in the 13CNMR spectrum of this substance ?

Isoamyl acetate is the primary component of artificial banana flavor. Which signals will be in the positive phase, negative phase, or nonexistent in normal 13C NMR, DEPT-90, and DEPT-135 of isoamyl acetate?

Which of the following compounds will show intense signals in 2250CM^-1 and why? OH H3C- H3C- EN -CH3 H3C H3C

5. Did you have unknown A or B? Which unknown does your NMR indicate that you isolated and how do you know (include what types of chemical shifts led you to this conclusion)? Include your worked up (MestreNova: peak pick, integrate, normalize, and reference to chloroform or DMSO) and annotated (assign the peaks) NMR to the worksheet for this question. You must do the work up yourself, any copying or using of worked up data from another student is academic misconduct. Attach your NMR to this question.
