In which reaction, Diborane, (BH₃)₂ reacts with alkene followed by reaction with hydrogen peroxide (H₂O₂) and a base to give alcohol?

Hydroboration-oxidation reaction

Diborane (BH₃)₂ reacts with alkenes to give trialkyl boranes as addition product. This is oxidized to alcohol by hydrogen peroxide (H₂O₂) in the presence of aqueous sodium hydroxide (NaOH).
