Chemistry - Coordination Chemistry Question with Solution | TestHub
Complex has two isomers I and II. Isomer I and II have and in their co-ordination sphere respectively. Choose CORRECT statement :-
Options:(select one or more)
Answer:
Solution:
Given complex: CoClBr⋅5NH₃ exists as two isomers:
Isomer I:
Isomer II:
Both isomers differ in the ion present inside and outside the coordination sphere, so they show ionisation isomerism. Hence, (A) is correct.
Both complexes have coordination number 6 with formula , so they do not show geometrical isomerism. Hence, (B) is correct.
Primary valency (ionisable valency) is satisfied by outer sphere ions; in both cases, it is satisfied by Cl⁻ and Br⁻. Hence, (C) is correct.
Isomer I releases Br⁻, not Cl⁻, so it does not give a white precipitate with AgNO₃. Hence, (D) is incorrect.
Correct Answer: (A), (B) and (C)
