NEET Chemistry Crystal Field Theory MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Imagine a diagram showing the splitting of d orbitals in an octahedral field according to Crystal Field Theory. The diagram displays two sets of orbitals labeled as 'e_g' and 't_{2g}'. Which of the following correctly describes the effect of ligand field strength on the energy difference between these orbitals?
A
Stronger ligand fields increase the energy difference.
B
Stronger ligand fields decrease the energy difference.
C
Weaker ligand fields increase the energy difference.
D
Ligand field strength does not affect the energy difference.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the crystal field splitting, Δo, depends on the field produced by the ligand. Stronger fields result in larger splitting of the d orbitals.
