Question
Specify the coordination geometry around and hybridisation of $$N$$ and $$B$$ atoms in a $$1:1$$ complex of $$B{F_3}$$ and $$N{H_3}$$
A.
$$N:$$ tetrahedral, $$s{p^3};B:$$ tetrahedral, $$s{p^3}$$
B.
$$N:$$ pyramidal, $$s{p^3};B:$$ pyramidal, $$s{p^3}$$
C.
$$N:$$ pyramidal, $$s{p^3};B:$$ planar, $$s{p^2}\,$$
D.
$$N:$$ pyramidal, $$s{p^3};B:$$ tetrahedral, $$s{p^3}$$
Answer :
$$N:$$ tetrahedral, $$s{p^3};B:$$ tetrahedral, $$s{p^3}$$
Solution :
$${H_3}N \to B{F_3}$$ where both $$N,B$$ are attaining tetrahedral geomerty.
