$[PdCl_4]^{2-} \Rightarrow dsp^2$

Vedclass · Answer

(A) $1$. For $[PdCl_4]^{2-}$,$Pd^{2+}$ is a $4d^8$ ion. Since $Pd$ is a $4d$ series metal,it always forms square planar complexes with $dsp^2$ hybridization. This is correct.$2$. For $[PtCl_4]^{2-}$,$Pt^{2+}$ is a $5d^8$ ion. Like $Pd^{2+}$,it forms square planar complexes with $dsp^2$ hybridization,not $sp^3$. This is incorrect.$3$. For $[Fe(NH_3)_6]^{2+}$,$Fe^{2+}$ is a $3d^6$ ion. $NH_3$ is a strong field ligand,but for $Fe^{2+}$,it is not strong enough to force pairing in the $3d$ orbital to form $d^2sp^3$. It forms an outer orbital complex $sp^3d^2$. This is incorrect.$4$. For $[Co(H_2O)_6]^{3+}$,$Co^{3+}$ is a $3d^6$ ion. $H_2O$ is a weak field ligand,so it forms an outer orbital complex $sp^3d^2$. This is correct.Note: Both $A$ and $D$ are technically correct based on standard coordination chemistry principles. However,$A$ is a classic example of $4d$ metal behavior.

$A$. $[CoF_6]^{3-}$	$M$. $sp^3d^2$,paramagnetic
$B$. $[Mn(CN)_6]^{3-}$	$N$. $sp^3d^2$,diamagnetic
$C$. $[Co(C_2O_4)_3]^{3-}$	$O$. $d^2sp^3$,paramagnetic
$D$. $[Zn(H_2O)_6]^{2+}$	$P$. $d^2sp^3$,diamagnetic
