Vedclass · Answer

(B) $(i)$ The number of unpaired electrons in $[Cr(H_2O)_6]^{3+}$ is $3$.The magnetic moment $\mu = \sqrt{n(n+2)} = \sqrt{3(3+2)} = \sqrt{15} \approx 3.87 \ BM$.$(ii)$ The number of unpaired electrons in $[Fe(H_2O)_6]^{2+}$ is $4$.The magnetic moment $\mu = \sqrt{4(4+2)} = \sqrt{24} \approx 4.90 \ BM$.$(iii)$ The number of unpaired electrons in $[Zn(H_2O)_6]^{2+}$ is $0$.Therefore,$[Fe(H_2O)_6]^{2+}$ has the highest magnetic moment value.

List-$I$ (Complex)	List-$II$ (Spin only Magnetic moment)
$A$. $[CoF_6]^{3-}$	$I$. $0$
$B$. $[Co(C_2O_4)_3]^{3-}$	$II$. $\sqrt{24}$
$C$. $[FeF_6]^{3-}$	$III$. $\sqrt{8}$
$D$. $[Mn(CN)_6]^{3-}$	$IV$. $\sqrt{35}$
	$V$. $\sqrt{15}$
