Answer:

Explanation:

The given complex is [Co(H2O)4(NH3)2]Cl3. Let's analyze the name of the complex according to the IUPAC rules for naming coordination compounds.

IUPAC Naming Rules:


Rule 1:

In an ionic complex, the cation is named first and then the anion. In this case, the cation is the coordination entity [Co(H2O)4(NH3)2] and the anion is Cl3.

Rule 2:

In the coordination entity, the ligands are named first and then the central metal ion. The ligands in this complex are H2O and NH3, and the central metal ion is Co.

Rule 3:

When more than one type of ligands are present, they are named in alphabetical order of preference without any consideration of charge.

Application of Rules:


According to rule 1, we name the cation first. The cation is the coordination entity [Co(H2O)4(NH3)2].

According to rule 2, we name the ligands first. The ligands in the complex are H2O and NH3. Since H2O comes before NH3 alphabetically, we write it first.

Now we have the name: tetraaqua diamine cobalt.

According to rule 2, we name the central metal ion, which is Co.

Now we have the name: tetraaqua diamine cobalt.

Finally, according to rule 1, we name the anion, which is Cl3.

Now we have the name: tetraaqua diamine cobalt chloride.

Since the central metal ion, cobalt, has a +3 charge, we indicate it in the name as cobalt(III).

Therefore, the correct name of the complex is diammine tetraaqua cobalt(III) chloride.

Answer: (D) diammine tetraaqua cobalt(III) chloride.
