NEET Chemistry Crystal Field Theory MCQ Question
Type: MCQ-diagram based-Hard-Class 12
In the diagram shown above, which of the following correctly represents the change in energy of e_g and t_2g orbitals due to crystal field splitting in an octahedral complex?
A
e_g increases by (3/5)Δo, t_2g decreases by (2/5)Δo
B
e_g decreases by (3/5)Δo, t_2g increases by (2/5)Δo
C
e_g increases by (2/5)Δo, t_2g decreases by (3/5)Δo
D
e_g decreases by (2/5)Δo, t_2g increases by (3/5)Δo
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, in an octahedral complex, the energy of e_g orbitals increases by (3/5)Δo and that of t_2g orbitals decreases by (2/5)Δo due to crystal field splitting.
