What type of isomerism is shown by the complex \([\text{Co(NH}_3)_6][\text{Cr(CN)}_6]\)?
The given coordination compound \([\text{Co(NH}_3)_6][\text{Cr(CN)}_6]\) exhibits ionization isomerism.
**Explanation:** Ionization isomerism arises when two complexes have the same molecular formula but yield different ions in solution. In this case, the cationic complex \([\text{Co(NH}_3)_6]^{3+}\) and the anionic complex \([\text{Cr(CN)}_6]^{3-}\) could interchange their ligands under different conditions, leading to a different complex with distinct properties.

Questions Asked in CBSE CLASS XII exam
A school is organizing a debate competition with participants as speakers and judges. $ S = \{S_1, S_2, S_3, S_4\} $ where $ S = \{S_1, S_2, S_3, S_4\} $ represents the set of speakers. The judges are represented by the set: $ J = \{J_1, J_2, J_3\} $ where $ J = \{J_1, J_2, J_3\} $ represents the set of judges. Each speaker can be assigned only one judge. Let $ R $ be a relation from set $ S $ to $ J $ defined as: $ R = \{(x, y) : \text{speaker } x \text{ is judged by judge } y, x \in S, y \in J\} $.
