\left[ {\mathrm{Co}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_5}\mathrm{Br}} \right]\mathrm{S}{\mathrm{O}_4}\mathrm{\;}

and

\left[ {\mathrm{Co}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_5}\mathrm{S}{\mathrm{O}_4}} \right]

\mathrm{Br}

are examples of which type of isomerism?

View answer and explanation

Correct option: D

Ionisation

The correct answer is D (Ionisation) because the complexes

{\left[ {\mathrm{Co}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_5}\mathrm{Br}} \right]\mathrm{S}{\mathrm{O}_4}\mathrm{\;}

and

{\left[ {\mathrm{Co}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_5}\mathrm{S}{\mathrm{O}_4}} \right]\mathrm{Br}}

exchange ions (Br- and SO42-) in the coordination sphere and outside it.
