Chemistry - Coordination Chemistry Question with Solution | TestHub
Which of the following statement(s) is/are correct.
Options:(select one or more)
Answer:
Solution:
Option B is correct: The spectrochemical series ranks ligands based on their ability to cause crystal field splitting, which is determined by the absorption of light by complexes.
Option D is correct: In a spherical crystal field, all d-orbitals are raised in energy compared to the isolated free metal ion due to repulsion from the ligands. This average energy is called the barycenter.
Option A is incorrect: Primary valencies are non-directional. The spatial arrangements are determined by secondary valencies (coordination number).
Option C is incorrect: For d⁴ to d⁷ systems, high spin (weak field) complexes are generally less stable than low spin (strong field) complexes due to smaller crystal field stabilization energy (CFSE).
