NEET Chemistry Crystal Field Theory MCQ Question
Which of the following combinations about crystal field theory is correct?
Crystal field splitting energy D_o is influenced by the ligand's field strength; e_g orbitals have higher energy than t_2g orbitals.
All ligands produce the same degree of field strength; anionic ligands always cause large splitting.
Crystal field theory explains the color of coordination compounds but does not account for covalent bonding.
The energy of the t_2g orbitals increases while e_g orbitals decrease in energy in an octahedral field.
Correct Answer
Detailed Explanation
Statement A is correct as it aligns with the provided context that explains the influence of ligand field strength on D_o and the relative energy of e_g and t_2g orbitals. Statement B is incorrect because the text states some ligands produce weak fields. Statement C is partially correct but does not emphasize the limitations adequately. Statement D incorrectly states the energy changes for the orbitals in an octahedral field.
