Question

So in this H-NMR spectra, wouldn't the two peaks farthest downfield be considered triplets? If they, then the correct answer doesn't make sense because the answer would have only doublets, correct?

NMR Spectroscopy: In the synthesis of acetylferrocene, some diacetylferrocene is produced. The 1H NMR spectrum of the diacetylferrocene is shown below. Three possible isomers of diacetylferrocene exist. From your knowledge of the 1H NMR spectrum of scetylferrocene, which isomer of diacetylferrocene is produced in this reaction? [NOTE the break in the spectrum] Complete the following table of spectral data in verify this structure and assign the peafcs[a,b,c] in your choice.

Explanation / Answer

only circled compound has three sets of protons and matching chemical shifts.

coming to point of splitting I too observe that splitting of sets B, C should cause triplets and doublets respectively
