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...

Construct a simulated 1H NMR spectrum for the given structural
formula. Drag the appropriate splitting patterns to the approximate
chemical shift positions; place the integration values in the small
bins above the associated chemical shift. Splitting patterns and
integrations may be used more than once, or not at all, as needed.
Likewise, some bins might remain blank. Note that peak heights are
arbitrary and do not indicate proton integrations.
