Vedclass · Answer

(C) The complex formed is bis(dimethylglyoximato)nickel$(II)$.$A$) It is a bright red precipitate, so statement $A$ is correct.$B$) It is insoluble in water and precipitates in basic medium, so statement $B$ is incorrect.$C$) $Ni^{2+}$ has a $3d^8$ configuration. In the presence of strong field ligands (dimethylglyoxime), it undergoes $dsp^2$ hybridization, resulting in a square planar geometry with $0$ unpaired electrons. Thus, statement $C$ is incorrect.$D$) In a square planar geometry, the $N-Ni-N$ bond angle is approximately $90^{\circ}$, so statement $D$ is correct.$E$) The complex contains $2$ five-membered chelate rings formed by the coordination of $Ni$ with the nitrogen atoms of the two dimethylglyoxime ligands. Statement $E$ is incorrect.Therefore, the incorrect statements are $B, C,$ and $E$.

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