Question

Which of the following complex species does involve d²sp³ hybridisation?

Options

• Linkage

• Ionisation

• Hydrate

• Coordination

Answer 1

Coordination

Explanation:

In d²sp³ hybridization occurs in coordination complexes with octahedral geometry (coordination number 6). In this hybridization, two d orbitals, one s orbital, and three p orbitals of the central metal ion combine to form six hybrid orbitals for bonding with ligands. While hydrates are a type of coordination complex, the hybridization specifically refers to the coordination of ligands, making coordination the correct answer.
