$Cu^{2+}$

Vedclass · Answer

(C) $Cu^{2+}$ ($3d^9$ configuration) forms complexes with the same magnetic moment and geometry irrespective of the nature of the ligand.The electronic configuration of $Cu^{2+}$ is $[Ar] 3d^9$. The $3d$ subshell contains one unpaired electron.Since the $3d$ subshell is almost completely filled,the incoming ligands cannot cause any pairing or redistribution of electrons in the $3d$ orbitals. Therefore,the number of unpaired electrons remains $1$ (magnetic moment $\mu = \sqrt{1(1+2)} = \sqrt{3} \approx 1.73 \ BM$) regardless of whether the ligand is strong or weak.Furthermore,the geometry of $Cu^{2+}$ complexes is typically determined by the number of ligands (e.g.,square planar for $4$ ligands due to Jahn-Teller distortion),which remains consistent for a given coordination number.

List-$I$	List-$II$
$I. [FeF_6]^{3-}$	$A. 1.73 \ BM$
$II. [Ti(H_2O)_6]^{3+}$	$B. 5.93 \ BM$
$III. [Cr(NH_3)_6]^{3+}$	$C. 0.00 \ BM$
$IV. [Ni(H_2O)_6]^{2+}$	$D. 2.83 \ BM$
$V. [Fe(CN)_6]^{4-}$	$E. 3.88 \ BM$
