Hydrogen bonding can be so confusing, and in this video we talk about some common mistakes. Hydrogen bonds are intermolecular forces between molecules. They form because one atom has a high electronegativity, so it gets a partial negative charge, and the hydrogen gets a partial positive charge.

In this video Paul Andersen describes the intermolecular forces associated with
dipoles. A dipole is a molecule that has split charge. Dipole may form associations with other dipoles, induced dipoles or ions. An important type of dipole-dipole
forces are hydrogen bonds.

In this video Paul Andersen describes the positive force intermolecular forces found between all atoms and molecules. As electrons are distributed unevenly it creates instantaneous dipoles which hold molecules together. This force even holds uncharged atoms (like Noble gases) together. London dispersion forces increase as surface area, molecule sizing and pi bonding increases.
