Question

Among the following species, identify the
isostructural paris
` NF_(3), NO_(3)^(-) , BF_(3), H_(3)^(+) O , HN_(3)`
A. `[NF_(3),NO_(3)^(-)] and [ BF_(3), H_(3)^(+) O]`
B. `[NF_(3), NH_(3)] and [NO_(3)^(-), BF_(3)]`
C. `[NF_(3),H_(3)^(+)o] and [NO_(3)^(-), BF_(3)]`
D. `[NF_(3), H_(3)^(+) O] and [HN_(3), BF_(3)]`

Answer 1

Correct Answer - C
`NF_(3) and H_(3) O^(+)` are pyramidal (`sp^(3)` hybridised )
whereas `NO_(3)^(-) and BF_(3)` are triangular planar `(sp^(2)`
hybridised ) `NH_(3)` has a bent structure
