Below is the H NMR spectra for the molecule styrene.
Consider if a hydroboration reaction was preformed on styrene.
How would the H NMR of the expected product change in comparison to
styrene? Circle which peaks from the styrene spectra would
disappear and not be present in the NMR of the product.
Draw the expected product. Describe the splitting pattern of
each new proton signal that would appear in the NMR of the
product.
