Question

The compounds $\left[PtC{l}_2{\left(N{H}_3\right)}_4\right]B{r}_2$ and $\left[PtB{r}_2{\left(N{H}_3\right)}_4\right]C{l}_2$ constitute a pair of:

• A. coordination isomers
• B. linkage isomers
• C. ionisation isomers
• D. optical isomers

Answer 1

The correct option is C ionisation isomers

Ionisation isomers are isomers that result from the interchange of ions inside and outside the coordination sphere.

Here, $B{r}^{-}$ and $C{l}^{-}$ ions are being interchanged. So, by definition, they are ionization isomers.
