IB Chemistry HL 2.2.16 Hl Hybridization Questions

Connect Lewis formulas and electron-domain geometry to sp, sp² or sp³ hybridization, then use the remaining p orbitals and bond angles to check unfamiliar structures.

Exam points

Explain hybridization as the mixing of atomic orbitals to form equivalent hybrid orbitals for bonding.
Assign sp, sp² or sp³ from Lewis structure, electron-domain geometry and characteristic bond angles in the specified atom or molecule.
Relate hybrid orbitals to σ-bond overlap and remaining unhybridized p orbitals that form π bonds in multiple-bond systems.
