Vedclass · Answer

(A) To be isoelectronic,species must have the same number of electrons.For $NO_3^-$: $7 + (3 	imes 8) + 1 = 32$ electrons.For $CO_3^{2-}$: $6 + (3 	imes 8) + 2 = 32$ electrons.Both $NO_3^-$ and $CO_3^{2-}$ have $32$ electrons,so they are isoelectronic.Both species have a central atom bonded to $3$ oxygen atoms with no lone pairs on the central atom,resulting in a trigonal planar geometry. Thus,they are isostructural.Therefore,the correct pair is $NO_3^-$ and $CO_3^{2-}$.

Which of the following pairs are isoelectronic and isostructural: $NO_3^-,$ $CO_3^{2-},$ $ClO_3^-,$ $SO_3$?
