Answer: London dispersion (van der Waals) forces.
- A London dispersion (van der Waals) forces
- B Hydrogen bonding between electronegative atoms and hydrogen
- C Ionic attraction between fully charged species
- D Dipole-dipole attraction exclusive to polar molecules
Correct answer: A. London dispersion (van der Waals) forces
Explanation: London dispersion forces arise from instantaneous dipoles and are present in all molecules, polar or non-polar.
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.
