Question

The complex ions \([Co(NH_3)_5(NO_2)]^{2+\) and \([Co(NH_3)_5(ONO)]^{2+}\) are called}

• A. Ionization isomers
• B. Linkage isomers
• C. Co-ordination isomers
• D. Geometrical isomers

Hint:

Linkage isomerism occurs when a ligand binds to a metal ion through different atoms, creating isomers that have the same molecular formula but distinct structural arrangements.

Answer 1

The Correct Option is B

Linkage isomerism arises when a ligand can coordinate to a metal ion in two distinct ways. In this case, \( NO_2 \) and \( ONO \) are two different forms of the same ligand, resulting in linkage isomerism. \bigskip Step 2: Hence, the correct answer is option (2). \bigskip
