NEET · Chemistry · STD 12 - 5. Co-ordination chemistry
Cobalt \((III)\) chloride forms several octahedral complexes with ammonia. Which of the following will not give test for chloride ions with silver nitrate at \(25\,^o C\) ?
- A \(CoCl_3 \cdot 5NH_3\)
- B \(CoCl_3 \cdot 6NH_3\)
- C \(CoCl_3 \cdot 3NH_3\)
- D \(CoCl_3 \cdot 4NH_3\)
Answer & Solution
Correct Answer
(C) \(CoCl_3 \cdot 3NH_3\)
Step-by-step Solution
Detailed explanation
Octahedral complex means it contains '\(6\)' coordinate bond. In \(\mathrm{CoCl}_{3} \cdot 3 \mathrm{NH}_{3}, \mathrm{Cl}\) cannot be outside from coordination sphere
