- AlH₃: Aluminum central atom bonded to three H atoms with no lone pairs on Al; each H has two electrons in the bond.
- BrF₃: Bromine central atom bonded to three F atoms with two lone pairs on Br; each F has three lone pairs and one bond.
- SiF₄: Silicon central atom bonded to four F atoms with no lone pairs on Si; each F has three lone pairs.
- SO₃: Sulfur central atom double-bonded to three O atoms with no lone pairs on S; each O has two lone pairs. (Resonance structures exist).
- CCl₄: Carbon central atom bonded to four Cl atoms with no lone pairs on C; each Cl has three lone pairs.
- CH₃Br: Carbon central atom bonded to three H atoms and one Br atom with no lone pairs on C; Br has three lone pairs.
