Question

The complex ions [Co(NH₃)₅ (NO₂)]²⁺ and [Co(NH₃)₅ ONO)]²⁺ are called ______.

Options

• Ionisation isomers

• Linkage isomers

• Co-ordination isomers

• Geometrical isomers

Answer 1

The complex ions [Co(NH₃)₅ (NO₂)]²⁺ and [Co(NH₃)₅ ONO)]²⁺ are called linkage isomers.

Explanation:

The complexes [Co(NH₃)₅ (NO₂)]²⁺ and [Co(NH₃)₅ ONO)]²⁺ are called linkage isomers because the NO₂ ligand is present. The ligand is ambidentate.
