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)?

1H NMR spectrum A corresponds to a molecule with the formula C3H5Cl.
1H NMR spectrum A corresponds to a molecule with the formula C3H5Cl. The compound shows significant IR bands at 730 (see Problem 53 of Chapter 11), 930, 980, 1630, and 3090 cm-1.

In 19F NMR spectroscopy, the F nuclei behave just like protons in 1H NMR spectroscopy in that they have a nuclear spin quantum number of 1/2. How many 19F NMR resonances do you expect for PF5? (Assume a static structure. In other words, the axial and equatorial do NOT rapidly scramble and change positions on the timescale of the NMR experiment.)

What proton nmr signals (at high field giving little overlap of signals) would be given by the vinyl hydrogens and the aromatic ring hydrogens of dibenzalacetone? You must indetify the sets of chemically equivalent protons, how many protons are in each set, what center of the signal of each set is expected to be in ppm, and what the multiplicity of each signal is expected to be. Do this with words and a structure, not with a drawn spectrum.
