Specify the coordination geometry around and hybridisation of `N` and `B` atoms in a 1:1 complex of `BF_(3)` and `NH_(3)` .

Options

A. N : tetrahedral, `sp^(3)` , B : tetrahedral, `sp^(3)`
B. N : pyramidal, `sp^(3)` , B : pyramidal, `sp^(3)`
C. N : pyramidal, `sp^(3)` , B : planar, `sp^(2)`
D. N : pyramidal, `sp^(3)` , B : tetrahedral, `sp^(3)`

Answer

A

Explanation

`[F-underset(F)underset(|)overset(F)overset(|)(B^("ө"))larrunderset(CH_(3))underset(|)overset(CH_(3))overset(|)(" N"^(+))-CH_(3)]` Both ‘B’ and ‘N’ sp3 tetrahedral.
