Question

What is meant by hydroboration-oxidation reaction? Illustrate it with an example.

Answer 1

Hydroboration-oxidation reaction is the addition of borane followed by oxidation.
For example, propene on hydroboration-oxidation gives propan-$1$-ol.
The reaction of propene with diborane gives trialkyl borane as an addition product.
Oxidation by hydrogen peroxide in presence of aqueous sodium hydroxide gives propan-$1$-ol.
