Vedclass · Answer

(A) $1$. Identify the ligands: There are $5$ ammine $(NH_3)$ ligands and $1$ nitro $(NO_2^-)$ ligand attached to the central metal atom.$2$. Determine the oxidation state of the central metal $Co$: 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 $0$. So,$x + 5(0) + 1(-1) + 2(-1) = 0$,which gives $x - 1 - 2 = 0$,so $x = +3$.$3$. Apply $IUPAC$ naming rules: Name the ligands alphabetically (ammine before nitro),then the metal with its oxidation state in Roman numerals,followed by the counter ion. The name is Pentaamminenitrito-$N$-cobalt$(III)$ chloride.

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