Question:
Is there any change in the hybridisation of B and N atoms as a result of the following reaction?

BF₃ + NH₃ → F₃B.NH₃

Answer:

The atomic number of boron is 5 & its electronic configuration in ground state is 1s²2s² 2p¹, & in excited state is 1s²2s¹ 2p², this means its one s & 2 p orbital will take part in hybridization to form sp² hybrid orbital.

Similarly N atom has atomic number of 7, with electronic configuration of 1s²2s² 2p³ in its ground state & in it excited state it has sp³ hybridization.

Now according to the question Boron & Nitrogen in reactant stage has sp² & sp³ hybridization respectively, but on the product side an adduct is formed, wherein Boron has changed it s hybridization to sp³ while Nitrogen remains in same sp³ hybridization
