JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
The correct order of energy of absorption for the following metal complexes is \(A: \left[ Ni ( en )_{3}\right]^{2+}, B :\left[ Ni \left( NH _{3}\right)_{6}\right]^{2+}, C :\left[ Ni \left( H _{2} O \right)_{6}\right]^{2+}\)
- A \(C < B < A\)
- B \(B < C < A\)
- C \(C < A < B\)
- D \(A < C < B\)
Answer & Solution
