According to the question, The hydroboration oxidation reaction is an organic chemical reaction which is employed for the conversion of alkenes into alcohols that are neutral. This is done via a two-step process which includes a hydroboration step and an oxidation step.
Hydroboration oxidation reaction is a two-step reaction in which alkene reacts with BH3 , THF (tetrahydrofuran) and hydrogen peroxide in a basic medium to give alcohol. This is done by a net addition (across the entire double bond) of water.
Hydroboration oxidation reaction mechanism can be considered as an anti-markovnikov reaction where a hydroxyl group attaches itself to the carbon which is less substituted.
So, according to this reaction, propene give n -propyl-alcohol.
