Chemical Bonding and Molecular Structure - Result Question 42
####43. Which of the following pairs of ions are isoelectronic and isostructural?
[2015]
(a) $ClO_3^{-}, CO_3^{2-}$
(b) $SO_3^{2-}, NO_3^{-}$
(c) $ClO_3^{-}, SO_3^{2-}$
(d) $CO_3^{2-}, SO_3^{2-}$
Show Answer
Solution:
- (c) $ClO_3{ }^{-}$and $SO_3{ }^{-2}$ both have same number of electrons (42) and central atom in each being $s p^{3}$ hybridised. Both are having one lone pair on central atom hence they are pyramidal.
