Question

Which of the following pairs of ions are isoelectronic and isostructural ? (A) CO2-3, NO-3 (B) ClO-3, CO2-3 (C) SO2-3, NO-3 (D) ClO-3, SO2-3

CO32- and NO-3 are isoelectronic as both contain 32 electrons and isostructural as both have trigonal planar structures with sp2 hybridisation of the central atom.

Q. Which of the following pairs of ions are isoelectronic and isostructural ?

$C O_{3}^{2 -}$ , $N O_{3}^{-}$

$Cl O_{3}^{-}$ , $C O_{3}^{2 -}$

$S O_{3}^{2 -}$ , $N O_{3}^{-}$

$Cl O_{3}^{-}$ , $S O_{3}^{2 -}$

$C O_{3}^{2 -}$ and $N O_{3}^{-}$ are isoelectronic as both contain $32$ electrons and isostructural as both have trigonal planar structures with $s p^{2}$ hybridisation of the central atom.

Q. Which of the following pairs of ions are isoelectronic and isostructural ?

CO32−​, NO3−​
