The IUPAC name for the complex[ Co(NO2)(NH3)5] Cl2is :a)pentaamminenit...
Understanding the Complex
The complex in question is [Co(NO2)(NH3)5]Cl2. To determine the correct IUPAC name, we need to analyze its components and oxidation state.
Components of the Complex
- Cobalt (Co): This is the central metal ion.
- Nitrito (NO2): This ligand is a bidentate ligand that can bind through nitrogen or oxygen. In this case, it's bound through nitrogen (hence the 'N' in the name).
- Ammonia (NH3): This is a neutral ligand, and there are five of them in the complex.
- Chloride (Cl2): This is the counter ion, indicating that the complex is a salt.
Oxidation State of Cobalt
To find the oxidation state of cobalt, we can set up the equation:
- Let x be the oxidation state of Co.
- The nitrito ligand contributes -1.
- Each ammonia ligand contributes 0.
- The total charge of the complex must balance with the counter ions (Cl2 contributes -2).
Thus, we have:
x - 1 + 0 = 0 (since the complex is neutral)
This simplifies to:
x - 1 = 0 → x = +1
However, since the complex has two Cl- ions, the oxidation state of cobalt is actually +3.
Correct IUPAC Name
Given that cobalt is in the +3 oxidation state and the nitrito ligand is attached through nitrogen, the correct IUPAC name is:
pentaamminenitrito-N-cobalt(III) chloride (option B).
Conclusion
- The use of "penta" indicates five ammonia ligands.
- "Nitrito-N" indicates the binding through nitrogen.
- "Cobalt(III)" reflects the +3 oxidation state.
- "Chloride" denotes the presence of Cl- as a counter ion.
Hence, the correct answer is option B, as it accurately represents the structure and oxidation state of the complex.
