Question

The co-ordination complex ions [Co(NH₃)₅ (NO₂)^2⊕ and [Co(NH₃)₅ (ONO)^2⊕ are ______ of each other.

विकल्प

• ionization isomers

• solvate isomers

• linkage isomers

• co-ordination isomers

Answer 1

The co-ordination complex ions [Co(NH₃)₅ (NO₂)^2⊕ and [Co(NH₃)₅ (ONO)^2⊕ are linkage isomers of each other.

Explanation:

In the complex [Co(NH₃)₅ (NO₂)^2⊕, the nitrite ligand \[\ce{(NO^-_2)}\] is attached through nitrogen, while in [Co(NH₃)₅ (ONO)^2⊕, it is attached through oxygen. Since the same ligand is bonded through different atoms, they are linkage isomers.
