2) Sketch what you would expect the 'H NMR of the following compound to look like, use labels from the structure and label correspondingly on the spectra you draw, make sure to include chemical shift, integration values and splitting patterns for your spectra. OH A Br H к L

How many atoms from the following molecule will be detected in a 1H NMR experiment? We are not asking for unique signals, just total number of atoms!OGMU 2020 ZI N

a) Make a table of the chemical shift, multiplicity and number of hydrogens for each 1H-NMR signal. b) Propose a structure consistent with the data and assign each proton in your structure to a signal in the NMR spectrum.

Explanation/Answer cannot be hand-drawn! Must be typed or illustrated digitally

the given structure, highlight the proton(s) responsible for each ¹H NMR signal in the spectrum shown with the appropriate color: singlet in , doublet in blue, and doublet of quartets in green. If a proton is responsible for any other type of signal, leave it un-highlighted. Note: You ma need to use all colors. H H C-H zy H H

1. How many proton signals would you expect to see in the ¹H-NMR spectrum of the following molecule? For each of the proton signals, predict the splitting pattern, assuming that you can see only 3-bond splitting.

Predict how many peaks you would expect to observe in the ‘H NMR,spectrum of the compound shown below and indicate the integration value you would expect to see for each peak. Please explain how you got the answer. (It may be useful to label each hydrogen atom using lowercase letters).

The following MS spectrum is for a compound which contains one oxygen atom (as well as C and H, of course, but no other atoms). Propose a structure which is consistent with this MS; also identify the species responsible for each peak whose numerical m/z is given (remember resonance!).
