NEET Chemistry Crystal Field Theory Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): In an octahedral complex, the energy of e_g orbitals increases by (3/5)Δ_o due to crystal field splitting. | Reason (R): Anionic ligands are expected to exert the greatest splitting effect according to the assumptions of Crystal Field Theory.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option B
Detailed Explanation
Both statements are true, but the reason does not explain the assertion as the energy increase of e_g orbitals is due to the geometry of splitting, not the type of ligands.
