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.)

Expert Solution

Depending upon on the spectrophotometer, if it can recognize axial and tlequitorial then it would happen as said above. In other case it would be a multiple(qutret of trplet or triplet of quatret.

Whatever I have explained above is 31P spectrum. F19 NMR as follows....

Both Fa and Fe couple with P separately.

Thank you and please let me know if you have any further queries.

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. (a) Deduce the structure of the molecule. (b) Assign each NMR signal to a hydrogen or group of hydrogens. (c) The “doublet” at δ = 4.05 ppm has J ≈ 6 Hz. Is this in accord with your assignment in (b)? (d) This “doublet,” upon five-fold expansion, becomes...

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)?
