Which of the following chloro complexes can be explained by dsp2 hybridization?

1. [PdCl4]2−
2. [FeCl4]2−
3. [CoCl4]2−
4. [NiCl4]2−

Correct answer: [PdCl4]2−

Solution

The complex [PdCl4]2− involves palladium in a +2 oxidation state, which allows for dsp2 hybridization, resulting in a square planar geometry. This hybridization occurs because palladium can utilize its d orbitals along with s and p orbitals to accommodate the four chloride ligands.
