Vedclass · Answer

(A) The spin-only magnetic moment of $3.83 \ BM$ corresponds to $n = 3$ unpaired electrons,indicating $Cr$ is in the $+3$ oxidation state. Thus,the formula is $Cr(H_{2}O)_{6}Cl_{3}$.Possible isomers are:$1$. $[Cr(H_{2}O)_{6}]Cl_{3}$: Reacts with $AgNO_{3}$ but shows no geometrical isomerism.$2$. $[Cr(H_{2}O)_{5}Cl]Cl_{2} \cdot H_{2}O$: Reacts with $AgNO_{3}$ but shows no geometrical isomerism.$3$. $[Cr(H_{2}O)_{4}Cl_{2}]Cl \cdot 2H_{2}O$: Reacts with $AgNO_{3}$ and shows geometrical isomerism (cis and trans forms).$4$. $[Cr(H_{2}O)_{3}Cl_{3}] \cdot 3H_{2}O$: Does not react with $AgNO_{3}$ (as no $Cl^-$ is outside the coordination sphere) and shows geometrical isomerism.The complex $[Cr(H_{2}O)_{4}Cl_{2}]Cl \cdot 2H_{2}O$ satisfies both conditions. Its $IUPAC$ name is Tetraaquadichloridochromium $(III)$ chloride dihydrate.

Complex $X$ of composition $Cr(H_{2}O)_{6}Cl_{n}$ has a spin-only magnetic moment of $3.83 \ BM$. It reacts with $AgNO_{3}$ and shows geometrical isomerism. The $IUPAC$ nomenclature of $X$ is
