The crystal field stabilisation energy (CFSE) for [CoCl6]4− is 18000c...
To determine the crystal field stabilization energy (CFSE) for [CoCl4]2-, we can use the relationship between the CFSE values of different coordination complexes.
The CFSE of [CoCl6]4- is given as 18000 cm-1. This means that the energy difference between the d orbitals in the presence of the ligands is 18000 cm-1.
1. CFSE for [CoCl6]4- = 18000 cm-1
Now, let's consider the [CoCl4]2- complex. This complex has four chloride ligands, which means it has a tetrahedral geometry.
2. CFSE for [CoCl4]2- = ?
Since the geometry is tetrahedral, the splitting of the d orbitals is different compared to an octahedral complex like [CoCl6]4-. In a tetrahedral complex, the t2g set of d orbitals (dxy, dyz, dzx) is lower in energy, while the eg set (dx2-y2, dz2) is higher in energy.
Therefore, we can expect that the CFSE for a tetrahedral complex will be less than the CFSE for an octahedral complex with the same metal ion.
3. CFSE for [CoCl4]2- < cfse="" for="" />
From the given options, the only value that satisfies this relationship is option D, which is 8000 cm-1.
Therefore, the CFSE for [CoCl4]2- is 8000 cm-1.
