Which of the following pairs of ions are isoelectronic and isostructural?
A
$CO_3^{2-}, SO_3^{2-}$
B
$ClO_3^-, CO_3^{2-}$
C
$SO_3^{2-}, NO_3^-$
D
$ClO_3^-, SO_3^{2-}$
Detailed Solution
$ClO_3^-$: 17 + 24 + 1 = 42 electrons; $SO_3^{2-}$: 16 + 24 + 2 = 42 electrons.
Both have $sp^3$ hybridisation with one lone pair (pyramidal).
So $ClO_3^-$ and $SO_3^{2-}$ are isoelectronic and isostructural.
