The IUPAC name [CoCl(NO2)(en)2]Cl isa)Chloridonitrobis (ethylenediamin...
The prefix bis indicates the presence of 2 ethylene diammine ligands. The oxidation state of Co is +3. One chloride ligand and one nitro ligand collectively have −2 charge. To maintain charge balance, the complex ion will have +1 charge.
The IUPAC name [CoCl(NO2)(en)2]Cl isa)Chloridonitrobis (ethylenediamin...
Explanation:
The given compound is [CoCl(NO2)(en)2]Cl. Let's break it down and analyze each part of the compound to determine its IUPAC name.
1. Central Metal Atom:
The central metal atom in this compound is cobalt (Co).
2. Ligands:
The compound contains three different ligands:
- Chloride (Cl-)
- Nitro (NO2-)
- Ethylenediamine (en)
3. Chloride Ligand:
The chloride ligand is named first since it is negatively charged. The prefix "chlorido" is used for chloride.
4. Nitro Ligand:
The nitro ligand is named as "nitrito-N" since the nitro group is coordinated to the metal atom through the nitrogen atom.
5. Ethylenediamine Ligand:
The ethylenediamine ligand is a bidentate ligand, meaning it can bind to the metal atom through two of its nitrogen atoms. The prefix "bis" is used to indicate this.
6. Oxidation State:
To determine the oxidation state of the cobalt atom, we need to consider the overall charge of the complex. Since the complex is neutral, the oxidation state of cobalt must be determined accordingly.
From the ligands, we can determine the charge contributed by each one:
- Chloride (Cl-) contributes a charge of -1
- Nitro (NO2-) contributes a charge of -1
- Ethylenediamine (en) is neutral
Since there is only one chloride ligand, it contributes a charge of -1. Therefore, the charge contributed by the rest of the ligands must be +1 to make the overall complex neutral.
7. IUPAC Name:
Based on the information above, the IUPAC name of the compound is "Chloridobis(ethylenediamine)nitrito-N-cobalt(III)chloride" (Option B).
