2. How many distinct signals would you expect from the following molecules? Select the correct answer. B A A B C D 'N' C Ꭰ D | 1 2 3 45678 0000000 O O O O O OOO OOOOOOOO OOOOOOOO

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 07 9 8 6 ¹HNMR 23) Reset Answer signals will observe for (2-bromopropyl)benzene?

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)

10

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?

#4) Using the following spectra and other information provided, identify the compound. Assign pertinent peaks in the spectra. Label the peaks on the spectrum and place the structure of the compound in the box on the right side of the spectrum - Identify correct compound - label proton spectrum - label carbon spectrum

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.
