Naming of K2[OsCI5N]
The correct name of K2[OsCI5N] is potassium pentachloroazoosmate(VI).
Explanation:
- K2: This indicates that the compound contains two potassium ions.
- Os: This indicates the presence of osmium in the compound.
- CI5: This indicates that there are five chlorine atoms in the compound.
- N: This indicates the presence of nitrogen in the compound.
To name the compound, we need to determine the oxidation state of the metal ion. Here, the oxidation state of Os is +6 because there are five chlorine atoms with an oxidation state of -1 each and one nitrogen atom with an oxidation state of -1, making the total negative charge -6. So, the positive charge on Os must be +6 to balance the negative charge.
Next, we need to name the ligands. The ligands are listed in alphabetical order, followed by the name of the metal ion. Here, the ligands are chloro and azoo. The prefix "pentachloro" indicates that there are five chlorine atoms, and the suffix "azo" indicates the presence of a nitrogen-nitrogen double bond. The ligands are listed in alphabetical order, so "azo" comes before "chloro". Therefore, the ligand name is "pentachloroazo".
Finally, we write the name of the compound by combining the names of the ligands and the metal ion. The name of the compound is "potassium pentachloroazoosmate(VI)".
Hence, the correct answer is option A - potassium pentachloroazoosmate(VI).
