Initially boron atom BF_{3} was in sp^2 hybridised. The valence orbital of boron in the excited state can be shown as:

And nitrogen atom in NH_{3} is sp^3 hybridised. The valence orbital of nitrogen in the excited state can be shown as:

Then after the reaction has occured the product F_{3}B.NH_{3} is formed by the hybridisation of 'B' changes to sp^3. However, the hybridisation of 'N' remains unchanged.
