H NMR For the diastereomers of 1,2-diphenyl-1,2-ethanediol: How do the H NMR spectra change between the meso diol and either the R,R or S,S diol? I know that they're different, but I'm unsure why. If possible it would be nice to see a possible H NMR spectra drawn out for these two. Thank you for your help.

The 1H NMR of ethanol in CDCl3 will consist of three signals in the spectra: a triplet at 1.25 ppm, a quartet at 3.72 ppm, and a broad singlet at 1.32 ppm. In DMSO-d6(deuterated DMSO) the broad singlet is found at 4.63 ppm. Why is there such a dramatic change in the singlet’s position (clearly describe what is happening with structure)?

Which of the following statements are TRUE for first-order analyses of NMR spectra (the type of analysis most commonly done). The spin-multiplicity of the proton NMR absorption of the methylene group in ethanol-OD is 4. The difference in absorption frequency is equal to or less than 6 J. Equivalent protons do not split each other. First-order multiplets are symmetrical, and their chemical shift is given by the position of the first peak in the multiplet. Carbon-13, an NMR-active nucleus, has...
