Question:
Among the following species, the correct set of isomolecular pairs are:
\[
\mathrm{XeO}_3, \, \mathrm{CO}_3^{2-}, \, \mathrm{SO}_3, \, \mathrm{H}_3\mathrm{O}^+, \, \mathrm{ClF}_3
\]
Among the following species, the correct set of isomolecular pairs are:
\[
\mathrm{XeO}_3, \, \mathrm{CO}_3^{2-}, \, \mathrm{SO}_3, \, \mathrm{H}_3\mathrm{O}^+, \, \mathrm{ClF}_3
\]
Show Hint
Isomolecular pairs in chemistry share the same molecular geometry and usually have similar electron domain distributions around the central atom.

The Correct Option is C
Solution and Explanation
The isomolecular pairs are those that have identical molecular shapes due to similar electron domain geometries. In this set:
- \(\mathrm{XeO}_3\) and \(\mathrm{H}_3\mathrm{O}^+\) both have trigonal pyramidal shapes.
- \(\mathrm{SO}_3\) and \(\mathrm{CO}_3^{2-}\) both have trigonal planar shapes.
