In which of the following pairs, the two spices are iso-structural?

Options

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

D

Explanation

`BrO_3^(-)`
Electron pair over the central atom ` = 3 + 1/2[7 - 6 + 1] rArr 4`
No. of atom bonded to the central atom = 3
Geometry will be pyramidal.
`XeO_3`
Electron pair ` = 3 + 1/2 [ 8 - 6] rArr 4`
No. of atom bonded to the central atom = 3
Geometry will be pyramidal.
