The d²sp² hydridisation shows which structure?

CONCEPT:

d²sp² Hybridization

• Hybridization occurs when atomic orbitals mix to form new hybrid orbitals, which influence the geometry of molecules.
• d²sp² hybridization involves the mixing of two d orbitals, one s orbital, and one p orbital from the valence shell.
• This type of hybridization is characteristic of square planar geometry in coordination compounds.

EXPLANATION:

• When a central metal atom undergoes d²sp² hybridization, the resulting hybrid orbitals arrange themselves in a square planar geometry to minimize electron pair repulsion.
• This geometry is commonly observed in coordination complexes with a coordination number of 4, where ligands are arranged in a planar square around the central metal atom.
• An example of a compound showing d²sp² hybridization and square planar geometry is [Ni(CN)₄]^2-.

Therefore, the structure resulting from d²sp² hybridization is square planar.
