Is there any change in the hybridization of B and N atoms as a result of the following reaction?BF3 + NH3 → F3B.NH3.

Answer»

Here, B atom in BF3 is sp2 hybridized and one of its p orbital is empty. N in NH3 is sp3 hybridized and are of its hybrid orbitals is occupied by a lone-pair of electrons. During the reaction a co-ordinate bond is formed due to one-side sharing of electron pair.

BF3 + NH3 → [F3B ←: NH3] → F3B ← NH3

There is no change in the hybridization of any of the two atoms in this reaction
