Question

Choose the molecular geometry of each type of hybrid orbital that forms.

When one s- and one p-orbital mix, the resulting hybrid orbitals have a
geometry.
When one s- and two p-orbitals mix, the resulting hybrid orbitals have a
geometry.
When one s- and three p-orbitals mix, the resulting hybrid orbitals have a
geometry.

Answer 1

- s + p → sp: linear geometry (2 hybrid orbitals, 180°)
- s + 2p → sp2: trigonal planar geometry (3 hybrid orbitals, 120°)
- s + 3p → sp3: tetrahedral geometry (4 hybrid orbitals, ≈109.5°)
