Answer:

See explanation and image attached

Explanation:

Alkenes react with borane (BH3) as shown in the image attached. Borane is a good electrophile since it is an electron deficient compound.

It can attack the electron rich pi bond. The attack of borane on the pi bond occurs as shown and leads to an addition reaction. Hydrogen and BH2^- are added across the double bond as shown.

The product of this reaction is shown in the image attached.
