Crystal field theory class 12 questions
WebApr 9, 2024 · Complete answer: The salient features of crystal field theory are: ∙ In a complex central metal atom or ion is surrounded by various ligands. ∙ Ligands are negatively charged ions or neutral molecules, having lone pair of electrons example- H 2 O, N H 3 ∙ Metal ions and ligands are considered point charge, their interaction is purely electrostatic. WebNov 6, 2024 · Best answer 1. In a complex, the central metal atom or ion is surrounded by various ligands which are either negatively charged ions (F-,CI-,CN-, etc) or neutral molecules (H2O,NH3, en, etc.) and the most electronegative atom in them points towards central metal ion. 2.
