Vedclass · Answer

(A) The magnitude of crystal field splitting energy $(\Delta_o)$ in an octahedral complex depends on several factors:$1.$ The nature of the ligand: Strong field ligands cause larger splitting than weak field ligands.$2.$ The charge on the metal ion: Higher oxidation states of the metal ion lead to greater splitting.$3.$ The transition series: The splitting energy increases as we move down a group (from $3d$ to $4d$ to $5d$ series) because the $d$-orbitals become more extended and interact more strongly with ligands.Therefore,all three factors $(I, II, III)$ influence the magnitude of the crystal field stabilisation energy.

The magnitude of crystal field stabilisation energy in octahedral field depends on :
$I.$ The nature of the ligand
$II.$ The charge on the metal ion
$III.$ Whether the metal is in the first,second or third row of the transition elements
