Intermolecular Forces in Ethanol - Hydrogen Bonding Visualization #3645146 (License: Personal Use)

This 3D ball-and-stick model depicts four ethanol (C₂H₅OH) molecules interacting through hydrogen bonds-represented by green dotted lines connecting the hydroxyl hydrogen of one molecule to the oxygen of another. The red spheres are oxygen atoms, black are carbon, and white are hydrogen. Such interactions significantly influence boiling point, solubility, and viscosity.

Used in educational chemistry resources (e.g., textbooks, MOOCs, lab guides) to illustrate non-covalent interactions; targets high school to undergraduate learners studying molecular structure and physical chemistry.
