Vedclass · Answer

(B) In $BF_3$,the boron atom is $sp^2$ hybridized and possesses an empty $p_z$ orbital. When $BF_3$ reacts with $NH_3$,the lone pair of electrons from the nitrogen atom in $NH_3$ is donated into the empty $p_z$ orbital of boron. This coordinate covalent bond formation changes the geometry of boron from trigonal planar to tetrahedral. Consequently,the hybridization of boron changes from $sp^2$ to $sp^3$.

The formation of molecular complex $BF_3-NH_3$ results in a change in hybridization of boron
