Question

[Co(NH₃)₅(SO₄)]Br and [Co(NH₃)₅Br]SO₄ are examples of

• A. ionization isomers
• B. linkage isomers
• C. optical isomers.
• D. coordination isomers.

Answer 1

The Correct Option is A

Ionization isomers are compounds that contain the same components, but the ions are arranged differently in the crystal structure, resulting in the exchange of ions between the cation and anion.

• [Co(NH₃)₆(SO₄)]Br and [Co(NH₃)₆]BrSO₄ are examples of ionization isomers because the sulfate and bromide ions have swapped positions between the cation and the anion in the two complexes.
• Linkage isomers involve ligands that can coordinate to the metal through different atoms, which is not the case here.
• Optical isomers are mirror images of each other, which is not applicable here because the two complexes are not non-superimposable mirror images.
• Coordination isomers refer to different coordination spheres around the metal center, which also does not apply in this case.

Thus, the correct answer is (A) ionization isomers.
