Due to increase in polarising power of the metal ion

Vedclass · Answer

(B) According to Fajan's rule,the covalent character of an ionic bond increases with an increase in the charge density of the cation.As the oxidation state of the transition metal increases,the size of the metal ion decreases and its charge increases.This leads to a higher charge-to-size ratio,which increases the polarising power of the metal ion.The metal ion then distorts the electron cloud of the halide ion more effectively,resulting in greater covalent character in the metal-halide bond.

List-$I$ ($\text{Transition metal ion}$)	List-$II$ ($\text{Spin only magnetic moment (B.M.)}$)

$B$. $V^{2+}$	$II$. $0.00$
$C$. $Ni^{2+}$	$III$. $1.73$
