Write the formula of the noble gas species that is isostructural with (i) `ICl_(4)^(-)` (i) `BrO_(3)^(-)`

Answer

The species which have same number of electrons are called isoelectronic.The species which have same structure and hybridisation are callled isostructural.
(a)`ICI_(4)^(-)` and `XeF_(4)` are square planar with `sp^(3)d^(2)` hybridisation.
(b)`IBr_(2)^(-)` and `XeF_(2)` are linear with `sp^(3)d` hybridisation.
( c)`BrO_(3)^(-)` and `XeO_(3)` are pyramidal with `sp^(3)` hybridisation.
