A) \[SO_{3}^{2-},\text{ }CO_{3}^{2-},\text{ }NO_{3}^{-}\]
B) \[BO_{3}^{3-},\text{ }CO_{3}^{2-},\text{ }NO_{3}^{-}\]
C) \[C{{N}^{-}},\text{ }{{N}_{2}},\text{ }C_{2}^{2-}\]
D) \[PO_{4}^{3-},SO_{4}^{2-},ClO_{4}^{-}\]
Correct Answer: A
Solution :
Isoelectronic species have same number of electrons.\[SO_{3}^{2-}\]has\[42{{e}^{-}},CO_{3}^{2-}\]has\[32\text{ }{{e}^{-}}\]and \[NO_{3}^{-}\]has\[32\,{{e}^{-}}\]. Hence, these are not isoelectronic species.You need to login to perform this action.
