Vedclass · Answer

(B) $1$. Identify the ligands: There are $4$ water molecules (aqua) and $2$ chloride ions (chlorido). Alphabetically,'aqua' comes before 'chlorido'.$2$. Name the coordination sphere: The ligands are named as tetraaqua and dichlorido. The metal is chromium.$3$. Determine the oxidation state of $Cr$: Let $x$ be the oxidation state of $Cr$. The charge on $H_2O$ is $0$,$Cl$ is $-1$,and $NO_3$ is $-1$. So,$x + 2(-1) + 4(0) = +1$ (since $NO_3$ is $-1$,the complex ion is $+1$). Thus,$x - 2 = +1$,which gives $x = +3$.$4$. Combine: The name is tetraaquadichloridochromium $(III)$ nitrate.

The $IUPAC$ name of the complex $[CrCl_2(H_2O)_4]NO_3$ is:
