(a)
Interpretation: The structure of the major product formed from alkene indicated should be predicted.
Concept introduction: Hydroboration-oxidation involves the sequence of two reactions. The hydroboration stage involves the treatment of alkene with diborane that generates alkyl borane. In second stage hydrogen peroxide in alkaline medium is used to oxidize the alkyl borane produced in step 1 that leads to the synthesis of alcohols from
Hydroboration is essentially the addition of
