Chemistry - Coordination Chemistry Question with Solution | TestHub
The crystal field splitting, depends upon the field produced by the ligand and charge on the metal ion. Some ligands are able to produce strong fields in which case, the splitting will be large whereas others produce weak field and consequently result in small splitting of d-orbitals.
Which of the following statement is correct regarding above process?
Options:
Answer:
Solution:
Complex A, ²⁺, contains Co²⁺ ( high-spin configuration) with 3 unpaired electrons () due to NH₃ acting as a weak-field ligand for +2 cobalt.
Complex B, ²⁺, possesses a plane of symmetry because the bidentate ethylenediamine (en) ligand creates a symmetric structure, meaning it has 0 optically active isomers.
The total sum of optically active isomers in B (0) and unpaired electrons in A (3) equals 3, making statement (C) entirely correct.
