Vedclass · Answer

(D) $1$. The central metal ion is $Cu^{2+}$,which has an electronic configuration of $[Ar] 3d^9$.$2$. In the presence of $NH_3$ ligands,which are strong field ligands,the $Cu^{2+}$ ion undergoes $dsp^2$ hybridization.$3$. This results in a square planar geometry.$4$. The $3d^9$ configuration leaves one unpaired electron in the $3d_{x^2-y^2}$ orbital (or rather,the hole is in the $d_{x^2-y^2}$ orbital),making the complex paramagnetic with one unpaired electron.

List-$I$ (Tetrahedral Complex)	List-$II$ (Electronic configuration)
$A$. $TiCl_4$	$I$. $e^2, t_2^0$
$B$. $[FeO_4]^{2-}$	$II$. $e^4, t_2^3$
$C$. $[FeCl_4]^{-}$	$III$. $e^0, t_2^0$
$D$. $[CoCl_4]^{2-}$	$IV$. $e^2, t_2^3$

The complex ion $[Cu(NH_3)_4]^{2+}$ has which of the following geometries and electronic configurations?
