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

1. SO32− and NO3−
2. BF3 and NF3
3. BrO3− and XeO3
4. SF4 and XeF4

Correct answer: BrO3− and XeO3

Solution

Isostructural species have the same shape and hybridization. Both BrO3− and XeO3 are pyramidal with sp3 hybridization, making them isostructural.
