Among the following species, identify the isostuctural pairs
`NF_(3). NO_(3)^(-), BF_(3), H_(3)O, HN_(3)`

Options

A. `[NF_(3),NO_(3)^(-)]` and `[BF_(3)H_(3)O^(+)]`
B. `[NF_(3),HN_(3)]` and `[NO_(3)^(-),BF_(3)]`
C. `[NF_(3),N_(3)O^(+)]` and `[NO_(3)^(-),BF_(3)]`
D. `[NF_(3),H_(3)O^(+)]` and `[HN_(3)^(-),BF_(3)]`

Answer

C

Explanation

`NF_(3)` and `H_(2)O` have `sp^(2)` hybridisation `NO_(3)^(-)` and `BF_(3)` have `sp^(2)` hybridisation
