MCQChemistry

CBSE · Class 12 · Chemistry · Coordination CompoundsWhich of the following compounds exhibits linkage isomerism?

Step-by-Step Solution

Linkage isomerism arises in coordination compounds containing ambidentate ligands. Ambidentate ligands are those ligands that have two different donor atoms and can coordinate through either of them. Among the given options, [Co(NH3)5(NO2)]Cl2 contains the nitrite ion (NO2-), which is an ambidentate ligand that can coordinate through nitrogen (-NO2) or oxygen (-ONO). Thus, it shows linkage isomerism.
