Answer: Constructive interference of atomic wavefunctions.
- A Constructive interference of atomic wavefunctions
- B Destructive interference between two atomic orbital wavefunctions
- C Overlap restricted exclusively to spherical s orbitals
- D An arbitrary, unguided combination of orbitals
Correct answer: A. Constructive interference of atomic wavefunctions
Explanation: Constructive interference of atomic orbitals lowers energy to give bonding MOs; destructive interference raises energy to give antibonding MOs.
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.
