1.

In which of the following pairs, the two species are isostructural :A. `SF_(4)` and `XeF_(4)`B. `SO_(3)^(2-)` and `NO_(3)^(-)`C. `BF_(3)` and `NF_(3)`D. `BrO_(3)^(-)` and `XeO_(3)`

Answer» Correct Answer - D
`BrO_(3)^(-)`
Electron pair over the central the atom =`3+1/2[7-6+1] rArr =4`
Electron pair =3
No. of atom bonded to the central atom =4
Geometry will be pyramidal.
`XeO_(3)`
Electron pair =`3+1/2 [8-6] rArr 4`
Electron pair =3
No.of atom bonded to the central atom =4
Geometry will be pyramidal
