NEET Chemistry Crystal Field Theory MCQ Question
Consider a diagram of octahedral crystal field splitting where the d orbitals are labeled. Which of the following describes the change in energy for the e_g and t_2g orbitals due to crystal field splitting?
e_g orbitals increase by (3/5)Δo and t_2g orbitals decrease by (2/5)Δo
e_g orbitals decrease by (2/5)Δo and t_2g orbitals increase by (3/5)Δo
e_g orbitals decrease by (3/5)Δo and t_2g orbitals increase by (2/5)Δo
e_g orbitals increase by (2/5)Δo and t_2g orbitals decrease by (3/5)Δo
Correct Answer
Detailed Explanation
In octahedral crystal field splitting, the energy of the e_g orbitals increases by (3/5)Δo and that of the t_2g orbitals decreases by (2/5)Δo as per the NCERT context.
