Vedclass · Answer

(C) $1$. Identify the ligands: $NH_3$ (ammine),$CN^-$ (cyano),$O^{2-}$ (oxo),$O_2^{2-}$ (peroxo).$2$. Determine the oxidation state of $Cr$: Let it be $x$. The charge on $K$ is $+1$,$CN$ is $-1$,$O$ is $-2$,$O_2$ is $-2$,and $NH_3$ is $0$.$2(+1) + x + 2(-1) + 1(-2) + 1(-2) + 0 = 0$$2 + x - 2 - 2 - 2 = 0$$x - 4 = 0 \implies x = +4$.$3$. Order the ligands alphabetically: ammine,cyano,dioxo,peroxo.$4$. Combine: Potassium amminedicyanodioxoperoxochromate $(IV)$.
