Chemistry - Carbonyl compounds Question with Solution | TestHub

In the compounds$\left[\mathrm{C}\mathrm{o}\right(\mathrm{N}{\mathrm{H}}_3{)}_5\mathrm{N}{\mathrm{O}}_2]\mathrm{C}{\mathrm{l}}_2$, the oxidation state of cobalt is +3 and here 5$\mathrm{N}{\mathrm{H}}_3$ligand, a$\mathrm{N}{\mathrm{O}}_2$ligand are attached to the central atom. therefore its name is pentaamminecobalt$\left(\mathrm{I}\mathrm{I}\mathrm{I}\right)$chloride.
