Answer 2

Answer : The IUPAC name of $[Co(NH_3)_6]Cl_3$ is, hexaamminecobalt(III) chloride

Explanation :

Rules for naming of the coordination compounds :

• The ligand named first then metal.
• The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.
• The ligands are named in alphabetical order before the metal ion.
• Ligands that include a numerical prefix in the name use the prefixes bis for 2, tris for 3, or tetrakis for 4 to indicate their number.
• If the complex ion is an anion, we drop the ending of the metal name and add –ate.

In the given coordination compound, Co is the cobalt metal, $NH_3$ is the ligands named as ammine. and 'Cl' is the anion known as chlorine. The oxidation state of 'Co' is (+3).

Hence, the IUPAC name of $[Co(NH_3)_6]Cl_3$ is, hexaamminecobalt(III) chloride
