NEET Chemistry Crystal Field Theory MCQ Question

Type: MCQ-diagram based-Easy-Class 12

In the context of Crystal Field Theory, consider an octahedral complex where the d orbitals of a metal ion experience splitting. If the energy separation is denoted by Δo, which orbitals increase in energy by (3/5)Δo?

Question diagram
A

e_g orbitals

B

t_2g orbitals

C

s orbitals

D

p orbitals

Correct Answer

Option A

Detailed Explanation

In an octahedral field, the energy of the two e_g orbitals increases by (3/5)Δo while the energy of the three t_2g orbitals decreases by (2/5)Δo, as described in the NCERT context.
