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.

Use
the proton NMR and carbon 13 resonances to identify the two
different isomers of the molecule with the formula: C5O2H10
These two isomers are different! Do not draw the same
structure for both!
1) draw the isomer and label the proton NMR that corresponds
with the structure proposed.
2) draw the second isomer and label the proton NMR that
corresponds with the structure proposed.
