AIPMT PRELIMS 2008 Chemistry Crystal Field Theory MCQ Question
Type: MCQ-conceptual-Hard-Class 12
In which of the following co-ordination entities the magnitude of Δ₀ (CFSE in octahedral field) will be maximum? (Atomic number of Co=27)
A
[Co(CN)₆]³⁻
B
[Co(C₂O₄)₃]³⁻
C
[Co(H₂O)₆]³⁺
D
[Co(NH₃)₆]³⁺
Correct Answer
Option A
Detailed Explanation
The magnitude of Δ₀ is highest for ligands that are strong field ligands, such as CN⁻, which causes a large splitting of d-orbitals.
