Answer: Head-on (axial) overlap of orbitals.
- A Head-on (axial) overlap of orbitals
- B Lateral (side) overlap under typical conditions
- C Ionic transfer according to standard textbooks
- D Metallic orbital in general practice
Correct answer: A. Head-on (axial) overlap of orbitals
Explanation: Sigma bonds form by head-on overlap of atomic orbitals along the internuclear axis.
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.
