Answer 2

(Option c) the statement about hydroboration of propene incorrect is c) The Addition of a B-H O bond to the Alkene is Markovnikov's addition.

• BH3 is known to act as an electrophile i.e. it accepts electrons from nucleophiles.
• After hydroboration process, if hydrogen peroxide is allowed to react with propene, it results in propan-1-ol.
• Alkenes are electron donors and they are nucleophiles.
• Addition of a B-H O bond to the Alkene is an example of anti-Markovnikov's addition.
