Vedclass · Answer

(A) $1$. Identify the ligands: There are $5$ ammonia $(NH_3)$ ligands,named as 'pentaammine',and $1$ $NCS^-$ ligand,named as 'thiocyanato-$N$' because it is bonded through the nitrogen atom.$2$. Determine the oxidation state of the central metal atom $(Co)$: Let the oxidation state be $x$. The charge on $NH_3$ is $0$,$NCS^-$ is $-1$,and $Cl^-$ is $-1$. The total charge of the complex is $0$. So,$x + 5(0) + (-1) + 2(-1) = 0$,which gives $x - 3 = 0$,so $x = +3$.$3$. Assemble the name: The name is written as 'pentaammine(thiocyanato-$N$)cobalt$(III)$ chloride'.
