NEET Chemistry Crystal Field Theory MCQ Question

Type: MCQ-numerical-Medium-Class 12

In an octahedral complex, the energy of the e_g orbitals increases by a certain amount due to crystal field splitting. If the crystal field splitting energy (Δo) is 20000 cm⁻¹, what is the energy increase (in cm⁻¹) for the e_g orbitals?

A

12000 cm⁻¹

B

8000 cm⁻¹

C

4000 cm⁻¹

D

16000 cm⁻¹

Correct Answer

Option A

Detailed Explanation

The energy of the e_g orbitals increases by (3/5)Δo. With Δo = 20000 cm⁻¹, the increase is (3/5) * 20000 = 12000 cm⁻¹.
