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) , H_(3)O^(+) ] and [NO_(3)^(-) BF^(3)]`
D. `[NF_(3). H_(3)O^(+0)] and [HN_(3) , BF_(3)]`

Answer

C

Explanation

Isostructural pairs are the species that have the same electron-pair geometry and same shape.
