Vedclass · Answer

(A) $1$. Identify the ligands: $en$ is ethane-$1,2$-diamine,$Cl^-$ is chlorido,and $ONO^-$ is nitro-$O$.$2$. Determine the oxidation state of the central metal atom $(Co)$: Let the oxidation state be $x$. The complex is $[Co(en)_{2}(ONO)Cl]Cl$. The charge on $en$ is $0$,$ONO$ is $-1$,$Cl$ is $-1$,and the outer $Cl$ is $-1$. Thus,$x + 2(0) + (-1) + (-1) = +1$,so $x = +3$.$3$. Arrange ligands alphabetically: Chlorido comes before ethane-$1,2$-diamine,which comes before nitro-$O$.$4$. Combine the parts: Chloridobis(ethane-$1,2$-diamine)nitro-$O$-cobalt$(III)$ chloride.

As per $IUPAC$ norms,the name of the complex $[Co(en)_{2}(ONO)Cl]Cl$ is:
