Shown below is the peak list of chemical shifts, multiplicities,
numbers of protons (from integration), and coupling constants for
the 1H NMR spectrum in Question 4.
a) Draw the chemical structure of trans-4-nitrochalcone. Circle
the proton or protons that you would attempt to identify in the 1H
NMR spectrum as evidence that the expected trans-isomer was formed
(rather than the cis-isomer).
b) Identify the peak or peaks in the peak list that
correspond(s) to the proton or protons circled in...

Analyze the spectrum below and using the integrations and chemical shifts, assign the protons for the structure shown. If any of the four labels are incorrect, you will see a red X on the top left corner of the spectra. The doublet at 4.1 ppm, upon expansion, shows a doublet of triplets. Explain this extra splitting. The doublet at 4.1 ppm is...
