Among the following species, identify the isostructural parisNF_(3), NO_(3)^(-) , BF_(3), H_(3)^(+) O , HN_(3)

Answer»

`[NF_(3),NO_(3)^(-)] and[ BF_(3), H_(3)^(+) O]`
`[NF_(3), NH_(3)] and [NO_(3)^(-), BF_(3)]`
`[NF_(3),H_(3)^(+)o] and [NO_(3)^(-), BF_(3)]`
`[NF_(3), H_(3)^(+) O] and [HN_(3), BF_(3)]`

Solution :`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
