Vedclass · Answer

(A) $1$. Identify the bridging ligand: The $OH^-$ group acts as a bridge between two $Cr$ centers,denoted as $\mu$-hydroxo.$2$. Identify the coordination spheres: Each $Cr$ is bonded to $5$ $NH_3$ molecules,so we use the prefix 'bis' for two units of 'pentaamminechromium'.$3$. Calculate the oxidation state of $Cr$: Let the oxidation state of $Cr$ be $x$. The total charge is $+5$. The charge of $NH_3$ is $0$ and $OH^-$ is $-1$. Thus,$2x + (-1) = +5$,which gives $2x = +6$,so $x = +3$.$4$. Combine the parts: The name is $\mu$-hydroxo bis(pentaamminechromium$(III)$) ion.
