The spin-only magnetic moment of $[MnBr_4]^{x-}$ is $5.9 \ BM$. The geometry of the complex and $x$ respectively are

Which of the following complexes exhibits outer orbital hybridization?

$[Ni(PPh_3)_2Cl_2]$ is a paramagnetic complex. Identify the $INCORRECT$ statements about this complex.
$A$. The complex exhibits geometrical isomerism.
$B$. The complex is white in colour.
$C$. The calculated spin-only magnetic moment of the complex is $2.84 \ BM$.
$D$. The calculated $CFSE$ (Crystal Field Stabilization Energy) of $Ni$ in this complex is $-0.8 \Delta_0$.
$E$. The geometrical arrangement of ligands in this complex is similar to that in $Ni(CO)_4$.
Choose the correct answer from the options given below:

Match List-$I$ (Species) with List-$II$ (Hybrid orbitals used by the central atom in their formation) and select the correct answer.

List-$I$	List-$II$
$A. \, Ni(CN)_5^{3-}$	$1. \, sp^3$
$B. \, CuCl_5^{3-}$	$2. \, dsp^2$
$C. \, AuCl_4^-$	$3. \, sp^3d_{z^2}$
$D. \, ClO_4^-$	$4. \, d_{x^2-y^2}sp^3$

The correct order of $[FeF_6]^{3-}, [CoF_6]^{3-}, [Ni(CO)_4]$ and $[Ni(CN)_4]^{2-}$ complex species based on the number of unpaired electrons present is $:$

$[Cu(NH_3)_4]^{2+}$ has hybridisation and magnetic moment
