Predict the NMR of cyclododecanone. Include a chart of signals and splitting

Propose a structure consistent with each set of data.

Please help, I am struggling to find where the molecules shown, will create a peak on the NMR spectra graph.

Please don't provide hand wrettin solution...

If the molecule giving the ¹H NMR spectrum shown below has a total of 10 protons, how many protons are represented by peak II? 4 PPM

Please help answer the following question...thank you! Given the three potential constitutional isomers that you answered for problem 4, please examine the following 1H-NMR data, including integration and resonance assignments, and decide which of the molecules matches most closely with the spectral data.   **I have attached the answer from problem 4 as well.

b. In nature, COT adopts a "tub-shape," as was shown in class. Assuming the molecule distorts to this non-planar geometry is COT aromatic, anti-aromatic, or non-aromatic? C. George Olah and coworkers reported a relative of COT shown above, 1,4- dimethylcyclooctatetraene dication. The 'H NMR shows a set of 3 signals with relative integrations of 2:1:3 at 9.96 (two overlapped peaks), 9.90, and 3.98 ppm chemical shift. Explain why the signals at 9.96 and 9.90 show such a low field chemical shift (hint: it is not alone sufficient to say this is due to the positive charge). Second hint: use the a MO diagram you created in part a. to help answer this.

can someone pls explain the nmr for this strcture nylon 6, 10. please indicated the answers to the parts   i)what is the chemical shift does it shift to the left (downfield) suggests deshielding (more electronegative environment). Shift to the right side suggests shielding (less electronegative environment)  ii)what the Integration (area under the peaks). iii)The multiplicity (splitting) of peaks iv) what the shape of the peaks is it a  Singlet (1 peak ) where there will be no neighboring protons. Doublet (2 peaks )  with one neighboring proton.  Triplet (3 peaks ) with two neighboring protons.  or multiplet  more complex coupling patterns.

a) Interpreted the analytical data reported, you should include reference to theIR, and NMR chemical shifts, integration and observed splitting patterns

Match the four structures with the four IR spectra (by putting a proper letter in the box to the right of each spectrum). Use specific IR absorptions for various functional groups to identify the structures.
