Vedclass · Answer

(D) $1$. The complex ion is $[CoCl(ONO)(en)_2]^+$.$2$. The ligands are $Cl^-$ (chloro),$ONO^-$ (nitrito-$O$),and $en$ (ethylenediamine).$3$. Since there are two ethylenediamine ligands,we use the prefix 'bis'.$4$. The oxidation state of $Co$ is calculated as: $x + (-1) + (-1) + 2(0) = +1$,so $x = +3$.$5$. The complex is cationic,so the metal name remains 'cobalt'.$6$. Arranging ligands alphabetically: chloro,bis(ethylenediamine),nitrito-$O$.$7$. The correct $IUPAC$ name is chlorobis(ethylenediamine)nitrito-$O$-cobalt$(III)$ ion.

The correct name for the complex ion $[CoCl(ONO)(en)_2]^+$ is
