Question

Which of the following is an example of ionization isomerism?

Options

Choose one · Correct answer highlighted

[Co(NH₃)6]3+ and [CoCl(NH₃)5]2+ [CoCl₂(NH₃)4]+ (cis and trans) [Co(NH₃)5NO₂]2+ and [Co(NH₃)5ONO]2+ [Co(NH₃)5SO₄]Br and [Co(NH₃)5Br]SO₄ Correct

Explanation

Ionization isomerism involves exchange of ligands and counter ions. [Co(NH₃)5SO₄]Br and [Co(NH₃)5Br]SO₄ differ in which ion is inside/outside the coordination sphere.
