can you draw what the c13 NMR spectra graph would like look for 2, 2,2- trichloro-1-phenylethyl) acetate would look like, on pen and paper pls
4b Which carbon signal for the compound will appear at highest chemical shift. Why?
For the following 9 compounds (most of which were the ones used in this lab), tell me what peaks you would expect to see in the 'H-NMR spectrum of those compounds. I have provided table for you to fill out with approximate chemical shift (ppm units), peak multiplicity_(singlet, doublet, etc.) and integration of the signal (how many protons would give that signal). No IR data is required. In addition, tell me the number of 13C-NMR signals you would expect to see [specific 13C shifts are not required] Predict

look at this reaction (first image) If Product A is formed in this reaction, we expect to see a signal of the hydrogen atom of the alcohol functional group in the 1H NMR spectrum... (second image) Explain how this HSQC spectrum establishes that the signal of the hydrogen atom with the chemical shift of 2.22 ppm is the hydrogen atom of the alcohol functional group!
identify the groups of homotopic protons and from these, the group with the lowest and the group with the highest shift values. Give an estimate for these shift values.
