Vedclass · Answer

(B) Isoelectronic species have the same number of electrons,and isostructural species have the same geometry.$1$. Calculate the number of electrons:$SO_3^{2-}: 16 + (3 	imes 8) + 2 = 42 \ e^-$$ClO_3^-: 17 + (3 	imes 8) + 1 = 42 \ e^-$$CO_3^{2-}: 6 + (3 	imes 8) + 2 = 32 \ e^-$$NO_3^-: 7 + (3 	imes 8) + 1 = 32 \ e^-$$2$. Determine the structure:$SO_3^{2-}$ and $ClO_3^-$ both have $sp^3$ hybridization with one lone pair on the central atom,resulting in a pyramidal geometry.$CO_3^{2-}$ and $NO_3^-$ both have $sp^2$ hybridization with no lone pair on the central atom,resulting in a trigonal planar geometry.Therefore,$ClO_3^-$ and $SO_3^{2-}$ are both isoelectronic $(42 \ e^-)$ and isostructural (pyramidal).

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