Vedclass · Answer

(A) $1$. Identify the ligands: $Cl^-$ is chloro,$NO_2^-$ is nitro,and $en$ is ethylenediamine. Since there are two $en$ ligands,we use the prefix 'bis'.$2$. Determine the oxidation state of the central metal atom $(Co)$: Let the oxidation state be $x$. The charge on $Cl$ is $-1$,$NO_2$ is $-1$,$en$ is $0$,and the outer $Cl$ is $-1$. Thus,$x + (-1) + (-1) + 2(0) + (-1) = 0$,which gives $x = +3$.$3$. Arrange ligands alphabetically: 'chloro' comes before 'nitro'.$4$. Combine: The name is chloronitro bis(ethylenediamine)cobalt$(III)$ chloride.
