Assertion : According to crystal field theory , during complex formation , the d-orbitals split and form two sets of orbitals `t_(2g)` and `e_(g)` . Reason : Splitting of d-orbitals occurs only in case of strong field ligands .A. If both Assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is falseD. if both assertion and reason are false

Answer» Correct Answer - C
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 .
