Q. Of the following sets which does not contain isoelectronic species?
Chemical Bonding and Molecular Structure
A
$PO _{4}^{3-}, SO _{4}^{2-}, ClO _{4}^{-}$
12%
B
$CN ^{-}, N _{2}, C _{2}^{2-}$
21%
C
$SO _{3}^{2-}, CO _{3}^{2-}, NO _{3}^{-}$
59%
D
$BO _{3}^{3-}, CO _{3}^{2-}, NO _{3}^{-}$
8%
Solution:
Number of electrons in $SO _{3}^{2-}=16+3 \times 8+2=42$
Number of electrons in $CO _{3}^{2-}=6+3 \times 8+2=32$
Number of electrons in $NO _{3}^{-}=7+3 \times 8+1=32$
