Vedclass · Answer

$(D)$ $A: [NiCl_4]^{2-}, Ni^{2+}(3d^8)$, weak field ligand, $sp^3$ hybridization, tetrahedral geometry, paramagnetic (two unpaired electrons). Correct.
$B: [Ni(NH_3)_6]^{2+}, Ni^{2+}(3d^8)$, weak field ligand, $sp^3d^2$ hybridization, octahedral geometry, paramagnetic (two unpaired electrons). Correct.
$C: [Ni(CO)_4], Ni^0(3d^8 4s^2)$, strong field ligand $(CO)$, $sp^3$ hybridization, tetrahedral geometry, diamagnetic (all electrons paired). Incorrect (given as paramagnetic).
$D: [Ni(CN)_4]^{2-}, Ni^{2+}(3d^8)$, strong field ligand $(CN^-)$, $dsp^2$ hybridization, square planar geometry, diamagnetic (all electrons paired). Correct.
Thus, the correct sequences are $A, B$, and $D$.

List-$I$ (Molecules/ion)	List-$II$ (Hybridisation of central atom)
$A. PF_5$	$I. dsp^2$
$B. SF_6$	$II. sp^3d$
$C. Ni(CO)_4$	$III. sp^3d^2$
$D. [PtCl_4]^{2-}$	$IV. sp^3$

List-$I$ (Complex/ion)	List-$II$ (Shape/geometry)
$A$. $[Pt(Cl)_2(NH_3)_2]$	$I$. Octahedral
$B$. $[Co(NH_3)_6]Cl_3$	$II$. Trigonal bipyramidal
$C$. $[NiCl_4]^{2-}$	$III$. Square planar
$D$. $[Fe(CO)_5]$	$IV$. Tetrahedral
