sodium hexanitro cobaltate $(III)$

Vedclass · Answer

(B) $1$. Identify the cation: $Na^+$ is sodium.$2$. Identify the coordination entity: $[Co(NO_{2})_{6}]^{3-}$.$3$. The ligand is $NO_{2}^-$,which is named 'nitro' when bonded through nitrogen.$4$. There are $6$ such ligands,so the prefix is 'hexa'.$5$. The central metal is cobalt,and since the complex is anionic,it is named 'cobaltate'.$6$. Calculate the oxidation state of $Co$: $x + 6(-1) = -3$,so $x = +3$.$7$. Combining these,the $IUPAC$ name is sodium hexanitrocobaltate $(III)$.
