Lesson-specific diagram for London dispersion, dipole interactions, and hydrogen bonding. It visualizes the reasoning sequence tied to $\text{structure}\to\text{IMF}\to\text{property}$. Text alternative: Intermolecular forces explain trends in boiling point, viscosity, surface tension, and solubility without being confused with intramolecular bonds. Choose a representation that matches the chemical scale and evidence; do not infer more precision or mechanism than the data support.
