Vedclass · Answer

(B) $1$. Identify the ligands: There are $5$ ammine $(NH_3)$ ligands and $1$ chloro $(Cl^-)$ ligand. According to $IUPAC$ rules,ligands are named alphabetically: ammine before chlorido.$2$. Name the coordination sphere: $5$ ammine ligands are named as 'pentaammine' and $1$ chloro ligand is named as 'chlorido'.$3$. Determine the oxidation state of the central metal atom $(Co)$: Let the oxidation state be $x$. The charge on $NH_3$ is $0$ and $Cl$ is $-1$. The total charge of the complex is $+2$ (since there are $2$ chloride ions outside the sphere). Thus,$x + 5(0) + 1(-1) = +2$,which gives $x = +3$.$4$. Combine the parts: The name is 'pentaamminechloridocobalt $(III)$ chloride'.

Pick the correct $IUPAC$ name of $[Co(NH_3)_5Cl]Cl_2$.
