Question

Which of the following pairs of ions are isoelectronic and isostructural?

पर्याय

• \[\ce{CO^{2-}_3, NO^-_3}\]

• \[\ce{ClO^-_3, CO^{2-}_3}\]

• \[\ce{SO^{2-}_3, NO^-_3}\]

• \[\ce{ClO^-_3, SO^{2-}_3}\]

Answer 1

\[\ce{CO^{2-}_3, NO^-_3}\]

Explanation:

\[\ce{CO^{2-}_3}\] and \[\ce{NO^-_3}\] are isoelectronic (32 electrons) and Planar.
