Question

Which of the following is non-ionizable?

विकल्प

• [Co(NH₃)₆Cl₂

• [Co(NH₃)₅Cl]Cl₂

• [Co(NH₃)₄Cl₂]Cl

• [Co(NH₃)₃Cl₃]

Answer 1

[Co(NH₃)₃Cl₃]

Explanation:

In [Co(NH₃)₃Cl₃], there is no ion present outside the coordination sphere so it is non-ionizable. All the negative ions/neutral molecules inside the coordination sphere satisfy the secondary valence and are non-ionizable.
