What ia the Iupac name of [Cr(CN3)]CL3
tricyanochroniumchlorovi
Well, I guess you could call it "Cr(CN3)CL3" if you want to be literal, but a more proper and less tongue-twisting name would be "chromium(III) tricyanide trichloride". Don't worry, I won't make you say that three times fast!
The correct IUPAC name for the complex [Cr(CN3)]Cl3 is tricyanochromium(III) chloride.
Here's a step-by-step breakdown:
1. Identify the central metal atom/ion: The central metal atom in this complex is chromium (Cr).
2. Determine the oxidation state of the central metal ion: It is mentioned that the oxidation state of chromium in this complex is +3.
3. Name the ligand: The ligand in this complex is cyanide (CN-). The prefix "tri-" indicates that there are three cyanide ligands coordinated to the central metal ion.
4. Write the name of the ligand: The name of the ligand is "cyanide."
5. Write the name of the central metal ion with its oxidation state: The central metal ion is chromium with a +3 oxidation state.
Putting all the information together, we get the IUPAC name "tricyanochromium(III) chloride" for the complex [Cr(CN3)]Cl3.
To determine the IUPAC name of a compound, we need to follow the rules and guidelines set by the International Union of Pure and Applied Chemistry (IUPAC).
In the given compound, [Cr(CN3)]Cl3, we have a chromium (Cr) ion complexed with three cyanide (CN-) ligands, and it is also associated with three chloride (Cl-) ions.
Let's break down the compound and identify each component:
1. The central metal ion is chromium (Cr).
2. The ligands are cyanide ions (CN-).
3. The counter ions are chloride ions (Cl-).
According to the IUPAC nomenclature rules, we should start by identifying the ligands and then the central metal ion.
1. Start with the ligands:
- Cyanide is named as "cyano" according to the IUPAC rules.
- Since we have three cyanide ligands, we add the prefix "tri-" to indicate three.
2. Next, write the central metal ion:
- The metal ion is chromium (Cr).
Now, let's combine the names of the ligands and the central metal ion to form the IUPAC name:
- The name of the complex is "tricyanidochromium(III) chloride."
Please note that the Roman numeral (III) indicates the oxidation state of the chromium ion, and "chloride" represents the counter ions.
Therefore, the IUPAC name of [Cr(CN3)]Cl3 is "tricyanidochromium(III) chloride."
