Q3. Which of the following compound would exhibit coordination isomerism?
Answer : Option D
Explaination / Solution:
Coordination isomerism is exhibited the the compounds in which cationic and anionic species is coordination complex.
Q4. The kind of isomerism exhibited by [Rh(en)2Cl2][Ir(en)Cl4] and [Ir(en)3][RhCl6] is
Answer : Option D
Explaination / Solution:
There is exchange of ligands between the cationic and anion species in coordination sphere.
Q5. The complex with highest stability constant at 298K is
Answer : Option B
Explaination / Solution:
Stability is proportional to CFSE value which is dependent upon Δo value. CN− is stronger field which increases the CFSE.
