Current Question (ID: 18711)

Question:

$\text{The complex that can exhibit linkage isomerism is:}$

Options:

1. $[\text{Co} (\text{NH}_3)_5 \text{H}_2\text{O}] \text{Cl}_3$
2. $[\text{Co} (\text{NH}_3)_5 (\text{NO}_2)] \text{Cl}_2$
3. $[\text{Co} (\text{NH}_3)_5 \text{NO}_3] (\text{NO}_3)_2$
4. $[\text{Co} (\text{NH}_3)_5 \text{Cl}] \text{SO}_4$

Solution:

$\text{HINT: } -\text{NO}_2 \text{ is an ambidentate ligand.}$ $\text{Explanation:}$ $\text{STEP 1: Linkage isomerism is the existence of coordination compounds that have the same composition differing with the connectivity of the metal to a ligand.}$ $\text{STEP 2: } -\text{NO}_2 \text{ is an ambidentate ligand as it connect with metal by N or O atom. Ambidentate ligand show linkage isomerism.}$ $\text{The isomers are } [\text{Co} (\text{NH}_3)_5 (\text{NO}_2)] \text{Cl}_2 \text{ and } [\text{Co} (\text{NH}_3)_5 (\text{ONO})] \text{Cl}_2$ $\text{STEP 3: All other complexes have monodentate ligands, so no linkage isomers are possible.}$
