A)8)33 ppm
B)3)18 ppm
C)5)30 ppm
D)cannot be determined from information given

Question

The chemical shift in NMR spectroscopy is independent of the spectrometer's frequency. It is a relative measurement and remains the same (5.30 ppm in this case) regardless of whether a 60 MHz or a 100 MHz spectrometer is used.
