Vedclass · Answer

(B) $1$. Identify the ligands: There are $5$ ammonia $(NH_3)$ ligands,named as 'pentaammine',and $1$ nitro $(NO_2^-)$ ligand,named as 'nitrito-$N$'.$2$. Determine the oxidation state of the central metal atom $(Co)$: Let the oxidation state of $Co$ be $x$. The charge on $NH_3$ is $0$,the charge on $NO_2$ is $-1$,and the charge on $Cl$ is $-1$. The total charge of the complex is $0$. Thus,$x + 5(0) + 1(-1) + 2(-1) = 0$,which gives $x - 1 - 2 = 0$,so $x = +3$.$3$. Assemble the name: The ligands are listed alphabetically (ammine before nitrito). The metal is cobalt,followed by its oxidation state in Roman numerals in parentheses. The counter ion is chloride. Therefore,the name is pentaamminenitrito-$N$-cobalt$(III)$ chloride.

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