Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): For the same metal, same oxidation state and same ligands, the crystal field splitting energy in a tetrahedral complex ( _t ) is approximately 4 9 of that in an octahedral complex ( _o ). Reason (R): Tetrahedral complexes rarely form low-spin configurations. In the light of the above statements, ch

Step-by-step solution

Assertion (A) is a correct statement. According to Crystal Field Theory, for the same metal ion, same oxidation state and same ligands, the relationship between tetrahedral and octahedral crystal field splitting energies is given by _t = 4 9 _o . Reason (R) is also a correct statement. In tetrahedral complexes, the crystal field splitting energy ( _t ) is generally smaller than the pairing energy ( P ). As a result, electrons prefer to occupy higher energy orbitals rather than pairing up, so low-spin configurations
