JEE Main 2026 — 5 April, Morning Shift — Question 60

Given below are two statements :

Statement I : Each electron in eg\mathrm{e}_{\mathrm{g}} orbitals destabilizes the orbitals by +0.6Δ0+0.6 \Delta_{0} and each electron in the t2gt_{2 g} orbitals stabilizes the orbitals by −0.4Δ0-0.4 \Delta_{0} in an octahedral field on the basis of crystal field theory.

Statement II : All the d-orbitals of the transition metals have the same energy in their free atomic state but when a complex is formed the ligands destroy the degeneracy of these orbitals on the basis of crystal field theory.

In the light of the above statements, choose the correct answer from the options given below.

  1. Option A:

    Both Statement I and Statement II are correct

  2. Option B:

    Both Statement I and Statement II are incorrect

  3. Option C:

    Statement I is correct but Statement II is incorrect

  4. Option D:

    Statement I is incorrect but Statement II is correct

    Correct

Answer: D

Step-by-step solution

Statement-II The degeneracy of the d-orbitals is removed due to ligand electron-metal electron repulsions according to crystal field theory. Both the statement I and II are correct
