The major product of the following reaction sequence is :
Reagents imply (1) Hydroboration and then (2) Oxidation and Hydrolysis
Hydroboration is a syn- addition (hydrogen and boron ). Initially boron atom and Hydrogen atom are added to the double bond.
Above product on oxidative-hydrolysis using H2O2,OH− gives
Markovnikovi Syn-addition
Ans: B
