Which of the following pairs of ions are isoelectronic and isostructur

1.	Which of the following pairs of ions are isoelectronic and isostructural ?
Answer» `SO_(3)^(2-) , NO_(3)^(9-)` `ClO_(3)^(-), SO_(3)^(2-)` `CO_(3)^(2-), SO_(3)^(2-)` `ClO_(3)^(-) , CO_(3)^(2-)` SOLUTION :`SO_(3)^(2-) to SP^(3) to ` Pyramidal ` to 16 + 24 + 2 = 42 e^(-)` `CIO_(3)^(-) to sp^(3) to ` Pyramidal` to 17 + 24 + 1 = 42 e^(-)` `CO_(3)^(2-) to sp^(2) to ` TRIANGULAR planar ` to 6 24 + 2= 32 e^(-)` ` NO_(3)^(2-) to sp^(2) to ` Triangular planar ` to 7 + 24 + 1 = 32 e^(-)` Thus, `SO_(3)^(2-) and CIO_(3)^(-)` are isoelectronic and isostructureal .
