AP Chemistry Hybridization and Intermolecular Forces

What is hybridization?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate the bonding and lone pairs of electrons in a molecule.

Which intermolecular force is present in all molecules?

London dispersion force

What is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole interaction that occurs between molecules when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

What is the significance of London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules and are present in all substances, influencing boiling and melting points.

What is the VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell.
