Answer 1

Answer:

IUPAC name of [ C o ( N H 3 ) 4 C l 2 ] C l is tetraammine dichloro cobalt (III) chloride.

Answer 2

The IUPAC name of $[COCl_{2}(NH_{3})_{4}] Cl$ will be Tetraammine Dichloride cobalt (III) chloride.

• Chemical compounds known as coordination compounds are made up of a number of anions or neutral molecules that are connected to a central atom by coordinate covalent connections.
• A coordination entity is a chemical compound in which the core ion or atom (or the coordination center) is bound to a certain number of atoms, molecules, or ions.
• The central atoms and central ions are those atoms and ions to which a predetermined number of other atoms, molecules, or ions are linked.
• The ions, atoms, or molecules that are joined to the core atom or ion or the coordination center are referred to as ligands.
• The total number of sigma bonds connecting the ligands to the coordination center is indicated by the coordination number of the central atom in the coordination complex.
• The coordination sphere is defined as the sum of the coordination center, the ligands bound to the coordination center, and the net charge of the chemical complex.

The naming of coordination compounds:

• If the given compound is a salt, we need to name the cation first and then the anion.
• When we are naming a complex ion, first give a name to the ligand then the metal.
• Instead of ending in -ide, anionic ligands finish in -o.
• A few neutral ligands will have special names.
• The name of coordination complexes will be a single word.
• Use prefixes like di-, tri-, tetra-, and penta- appropriately for the number of ligands.
• We need to list ligands alphabetically.
• If a ligand is polydentate or its name contains a Greek prefix, put the ligand name in parentheses and use the alternate prefixes bis- for 2, tris- 3, tetrakis- for 4 to specific numbers of each ligand.
• We need to use a Roman numeral in brackets, right after the name of the metal without space to specify the metal’s oxidation state.
• Use the ending -ate if the metal is an anionic complex ion.

Hence, the name of the given coordination compound is Tetraammine Dichloride cobalt (III) chloride.
