Draw a splitting diagram for the Hb proton if Jbc=10 and Jba=5.

Short Answer

Expert verified

In a splitting diagram, the NMR peaks are depicted as vertical lines, and the effect of each of the splittings is represented one at a time.

Proton spectrum reading

In a splitting diagram, the NMR peaks are depicted as vertical lines, and the effect of each of the splittings is represented one at a time.

02

Split diagram for a given compound

  • In the splitting diagram, five signals will be seen.
  • The splitting diagram for b protons in the given compound is first to split into a doublet by c proton. Then these doublets are further split into triplets with the overlapping of one peak from both triplets. The intensities of overlapping peaks will be added on.

A signal is seen at 600 Hz from the TMS signal in an NMR spectrometer with a 300-MHz operating frequency.

a. What is the chemical shift of the signal?

b. What is its chemical shift in an instrument operating at 500 MHz?

c. How many hertz from the TMS signal is the signal in a 500-MHz spectrometer?

Identify the compound with a molecular formula C8H10O that gives the IR and H1NMR spectra shown here.

Determine the ratios of the chemically non-equivalent protons in a compound if the steps of the integration curves measure 40.5, 27, 13 and118 mm , from left to right across the spectrum. Draw the structure of a compound whose H1NMR spectrum would show these integrals in the observed order.

Compound A, with molecular formula C4H9Cl, shows two signals in its 13C NMR spectrum. Compound B, an isomer of compound A, shows foursignals, and in the proton-coupled mode, the signal farthest downfield is a doublet. Identify compounds A and B.
