Please predict the products for each of the
following reactions.
Clearly show the regiochemistry (Markovnikov
vs anti-Markovnikov) and stereochemistry
(syn- vs anti- or both).
If a mixture of enantiomers is formed, please
draw all the enantiomers.
Hint: In this case you must choose the best
answer to demonstrate the stereochemistry of
H2 addition.
