Provide structures that are consistent with the following 1H NMR spectra. Calculate the degree of unsaturation of each compound first. Assign the protons to their respective peaks.010 1H shift chart 304.pdf
2) Propose structures for the compounds that would be expected to generate the following 1H NMR spectra. Calculate the degree of unsaturation of each compound and assign the protons to their respective peaks.010 1H shift chart 304.pdf
Interpret the 1 H NMR spectra of tatraphenylcyclopentadienone below. Label the different types of protons and carbons for the compound and locate the signals for these nuclei on the spectras. Use the chemical shift and integral ratio to help with your peak assignments. Beacuse of signal overlap, you may not be able to assign individual protons/carbons in a compound to a separate signal in the spectrum, so in these cases unsepearted peaks in the spectrum are to be assigned to...

Assign as many peaks as possible in the IR, 1H NMR, and 13C NMR spectra. The spectra are for triphenylmethanol.
Assign the peaks in the 1H NMR shown below to the correct protons in molecule 2. The portuon of the NMR between 8-6.5 ppm has been magnified for easier viewing. 4) Assign the peaks in the 'H NMR shown below to the correct protons in molecule 2. The portion of the NMR between 8-6.5 ppm has been magnified for easier viewing. 2H 1H2H1H Зн molecule 2 Зн PPM
5) Assign the peaks in the 'H NMR spectrum of your product. Draw your structure on the NMR spectrum and label each set of inequivalent protons. Use these labels in assigning the peaks. In some cases the aromatic peaks may overlap, so it is OK to assign groups of protons to a series of overlapping peaks if necessary. Try to be as specific as possible in your assignment, though. Discuss in detail how the NMR spectrum is only consistent with...
