Question

Which kind of isomerism can be exhibited by the complex $\left[Co\right(N{H}_3{)}_{4}B{r}_2]Cl$ ?

• A. Geometrical and ionization
• B. Geometrical and linkage
• C. Hydrate and ionization
• D. Geometrical only

Answer 1

The correct option is A Geometrical and ionization

The complex $\left[Co\right(N{H}_3{)}_{4}B{r}_2]Cl$ possesses geometrical isomerism.

It can also show ionization isomerism as shown below:
$\left[Co\right(N{H}_3{)}_{4}B{r}_2]Cl$ and $\left[Co\right(N{H}_3{)}_{4}BrCl]Br$.
For linkage isomerism there should be an ambidentate ligand inside the coordination sphere.
For hydrate isomerism $H_{2}O$ must be present.
