NEET Chemistry Crystal Field Theory MCQ Question
Which of the following statements about Crystal Field Theory (CFT) is correct?
CFT explains the color and magnetic properties of coordination compounds based on ligand charge.
CFT assumes that anionic ligands exert the strongest splitting effects in all cases.
CFT accurately accounts for covalent bonding characteristics in coordination compounds.
CFT is limited by its assumption of ligands as point charges affecting the d-orbitals.
Correct Answer
Detailed Explanation
Statement D is correct as the NCERT context mentions that one of the weaknesses of CFT is its assumption that ligands are point charges, which does not consider covalent character. Statement A is incorrect as CFT explains properties based more on ligand field strength than charge alone. Statement B is misleading as anionic ligands are found at the low end of the spectrochemical series. Statement C is also incorrect since CFT does not adequately address covalent bonding.
