In which of the following pairs, the two species are isostructural :

Options

A. `BrO_3^(-) and XeO_3`
B. `SF_4 and XeF_4`
C. `SO_3^(2-) and NO_3^(2-)`
D. `BF_3 and NF_3`

Answer

A

Explanation

`BrO^-` and `XeO_3` are both pyramidal. All others have different geometries. For example, `SF_4` is trigonal bipyramidal and `XeF_4` is square planar, `SO_3^(2-)` is pyramidal while `NO_3^-` is trigonal planar: `BF_3` is trigonal planar and `NF_3` is pyramidal
