The compounds _{4}\right] \boldsymbol{B r}_{2} \) and _{4}\right] \boldsymbol{C
The compounds \( \left[\boldsymbol{P t C l}_{2}\left(\boldsymbol{N} \boldsymbol{H}_{3}\right)_{4}\right] \boldsymbol{B r}_{2} \) and \( \left[\boldsymbol{P t B r}_{2}\left(\boldsymbol{N H}_{3}\right)_{4}\right] \boldsymbol{C l}_{2} \) constitute a pair of:
- A. coordination isomers
- B. linkage isomers
- C. ionisation isomers
- D. optical isomers
Step-by-step solution
The two compounds have the same overall formula but differ in which anions are coordinated to the platinum center and which are present as counterions: in the first, Cl is inside and Br outside; in the second, Br is inside and Cl outside. This is a classic example of ionization isomerism, where isomers give different ions in solution.
