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.)

1) In H NMR spectroscopy, why is the peak for a vinyl proton, C=C-H, shifted downfield relative to that of an alkane proton, C(sp3)-H? Be sure to use the following terms in your answer: pi-electrons, induced magnetic field, and resonance. 2)  In H NMR spectroscopy, why is the peak for a -CH2F group shifted downfield relative to that for a -CH2Br group? Be sure to use the following terms in your answer: electronegative, deshielded, magnetic field, and frequency.

A proton and Carbon-13 NMR for 2-Phenethylamine is described. First, the proton NMR spectrum. The solvent is CDCL3, which is probably the peak around 7.192-1.1745. There is a quartet at 7.192, 7.189, 7.178, 7.1745 with an integrated value of 2.860. This might be the solvent peak. There is a triplet at 2.969, 2.956, 2.942 with an integrated value of 1.008. There is a triplet at 2.747, 2.733, 2.720 with an integrated value of 1.000. There is a multiplet at 1.267,...
