Chemistry-Crystal Field Theory
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?
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.
