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

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

(a)`SF_4`=irregular tetrahedral (`sp^3d`, one lone pair)
`XeF_4` square planar (`sp^3 d^2` , two lone pairs )
(b) `SO_3^(2-)`=pyramidal (`sp^3` , one lone pair)
`NO_3^-`=trigonal planar (`sp^2`)
(c )`BF_3` =trigonal planar `(sp^2)`
`NF_3`=pyramidal `(sp^3)`
(d)`BrO_3^-`=pyramidal (`sp^3`, one lone pair)
`XeO_3`=pyramidal (`sp^3`, one lone pair)
