Question

Which kind of isomerism is exibited by octahedral $\left[Co\right(N{H}_3{)}_{4}B{r}_2]Cl$?

• A. Geometrical and lonization
• B. Geometrical and optical
• C. Optical and lonozation
• D. Geometrical only

Answer 1

The correct option is A Geometrical and lonization

The octahedral complex $\left[Co\right(N{H}_3{)}_{4}B{r}_2]Cl$ exhibits geometrical as well as ionization isomerism.
The ionization isomers are $\left[Co\right(N{H}_3{)}_{4}B{r}_2]Cl$ and $\left[Co\right(N{H}_3{)}_{4}Cl]B{r}_2$
The geometrical isomers are cis and trans isomers.
