We’re being asked to determine the products of the given reaction.



Recall that alkenes are converted to alcohols via hydroboration-oxidation:



This occurs in three steps:

(1) electrophilic addition – the alkene attacks the boron compound, forming a borane. This does not follow Markovnikov’s rule, where boron ends up on the less-substituted carbon.


(2) oxidation – NaOH and H2O2 react with the intermediate to form the alcohol. The stereochemistry of this reaction is sys, where –OH and –H will be cis to each other.
