Vedclass · Answer

(D) $1$. Identify the ligands: There are $5$ ammine $(NH_3)$ ligands and $1$ nitrito$-N$ $(NO_2^-)$ ligand.$2$. Determine the oxidation state of the central metal atom $(Co)$: Let the oxidation state be $x$. The charge on $NH_3$ is $0$,$NO_2^-$ is $-1$,and $Cl^-$ is $-1$. The total charge of the complex is $0$. Thus,$x + 5(0) + 1(-1) + 2(-1) = 0$,which gives $x - 3 = 0$,so $x = +3$.$3$. Name the complex: The ligands are named in alphabetical order (ammine before nitrito$-N$). The metal is cobalt followed by its oxidation state in Roman numerals in parentheses. The counter ion is chloride.$4$. The correct name is Pentaammine nitrito$-N$-cobalt$(III)$ chloride.

The $IUPAC$ name for the complex $[Co(NO_2)(NH_3)_5]Cl_2$ is :
