Answer: sp3d.
- A sp3
- B sp3d
- C sp2
- D sp3d2
Correct answer: B. sp3d
Explanation: SF4 has 4 bond pairs and 1 lone pair (5 electron domains), requiring sp3d hybridisation and giving a see-saw shape.
VSEPR theory predicts molecular shape from the number of bonding and lone electron pairs around the central atom.
Concept context
Understand how atoms join to form molecules. Covers ionic and covalent bonding, VSEPR theory, hybridization (sp, sp², sp³), molecular orbital theory, bond polarity, and intermolecular forces like hydrogen bonding.
