Specify the co-ordination geometry around and hybridisation of `N` and ` B` complex of `NH_3` and `BF_3`,

Options

A. N : tetrahedral , `sp^(3)` , B : tetrahedral ,` sp^(3)`
B. N : Pyramidal, `sp^(3)` , : Pyramidal , `sp^(3)`
C. N : Pyramidal , `sp^(3)` , : Pyramidal , `sp^(3)`
D. N : tetrahedral , `sp^3` , B : tetrahedral , `sp^3`

Answer

A

Explanation

`underset(sp^3)(NH_3)+underset(sp^3)(BF_3)rarr [underset(sp^3)(H_3N) rarr underset(sp^3) (BF_3)]`
