D3) Provided below are the IR and 13C NMR (proton decoupled) spectra which you obtain from youranalysis of the purified product (NB: The 13C NMR spectrum does not contain a solvent peak or aTMS peak because it is in reality a simulated spectrum. However, for the purpose of the questionimagine it is a real spectrum). Did the reaction produce the expected product? Explain your answerusing evidence from both the IR and 13C NMR spectra?

By looking at the H1 NMR spectra, draw the structure for the solid organic unknown compound and explain the process you used to determine the identity of your compound. Show all H atoms and label each equivalent set of atoms as A, B, C etc in the structure. Then, calculate the expected chemical shift for each of the equivalent set of H atoms in the structure. Clearly label your calculations Note: (Clearly list the tables used, base shift values and what correction factors were used.)

Annotate the spectra with any and all relevant signals that demonstrate the relationship and support your answer choice.Explain the meaning behind your annotations and how they correspond to the structure you choose. thanks in advance
Part C Look at the NMR spectrum and list the structural characteristics you can determine from this spectrum. 10 5 8 (ppm) Part D Look at the set of spectra as a group and propose a structure of the compound.
Propose a structure that is consistent with the following 1H NMR spectra. In each case, the molecular formula is provided. For spectra with numbers at the bottom of the signal you will need to determine the integration, others with numbers above the signal integration has been determined for you.
1. How would you differentiate between the following sets of molecules by IR and ¹H NMR? Consider: IR frequency and shape/intensity and NMR chemical shift, integration, and splitting.
