Vedclass · Answer

(C) The complex $[NiCl_2\{P(C_2H_5)_2(C_6H_5)\}_2]$ contains $Ni^{2+}$ with the electronic configuration $[Ar] 3d^8$.In the paramagnetic state,the complex adopts a tetrahedral geometry with $sp^3$ hybridization,where the two unpaired electrons in the $3d$ orbitals result in paramagnetism.In the diamagnetic state,the complex adopts a square planar geometry with $dsp^2$ hybridization,where all electrons are paired,resulting in diamagnetism.Therefore,the coordination geometries in the paramagnetic and diamagnetic states are tetrahedral and square planar,respectively.

$NiCl_2\{P(C_2H_5)_2(C_6H_5)\}_2$ exhibits temperature-dependent magnetic behaviour (paramagnetic/diamagnetic). The coordination geometries of $Ni^{2+}$ in the paramagnetic and diamagnetic states are respectively
