### NEET 2016 Phase 2

Which of the following pairs of ions is isoelectronic and isostructural ?
A
$C{O_3}^{2 - },\,\,N{O_3}^ -$
B
$C{lO_3}^{2 - },\,\,C{O_3}^{2 - }$
C
$S{O_3}^{2 - },\,\,N{O_3}^ -$
D
$Cl{O_3}^ - ,\,\,S{O_3}^{2 - }$

## Explanation

$CO^{2-}_3$; 6 + 24 + 2 = 32; sp2; trigonal planar

$N)_3^-$ : 7 + 24 + 1 = 32; sp2, trigonal planar

So, these are isoelectronic as well as isostructural.
