Assertion : According to crystal field theory, during complex formation, the d-orbitals split in octahedral field to form two sets of orbitals `t_(2g)` and `e_(g)`.
Reason : Splitting of d-orbitals occurs only in case of strong field ligands.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct, but (R) is not the correct explanation of (A).
C. If (A) is correct, but(R) is incorrect.
D. If both (A) and (R) are incorrect.

Answer

C

Explanation

Splitting of orbitals takes place for both weak and strong field ligands. Pairing of electrons in these orbitals depends on the strength of the field.
