Among the following species identify the isostructural pairs `NH_(3), NO_(3)^(Theta) ,BF_(3) ,H_(3) O^(o+) , N_(3) H` .

Options

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

Answer

C

Explanation

Therefore, `NF_(3), H_(3)O^(+)` and `BF_(3), NO_(3)^(-)` pairs have same shape.
