Classify each property as associated with a liquid that has strong or weak intermolecular forces. a. high viscosity
b. low boiling point
c. low viscosity
d. high boiling point
e. high surface tension
f. low surface tension
g. low vapor pressure high vapor pressure

Strong intermolecular forces: High viscosity, high boiling point, high surface tension, low vapour pressure.

Weak intermolecular forces: Low viscosity, low boiling point, low surface tension, high vapour pressure.

Explanation:

Intermolecular forces refers to the forces of attraction or repulsion between neighboring particles such as atoms, molecules and ions in a substance. The four main intermolecular forces are as ionic bonds, hydrogen bonding, dipole-dipole interactions and London dispersion forces.

Viscosity: is the resistance or opposition a fluid provides to the tendency to flow i.e. the tendency of neighboring molecules to move relative to one another. Stronger intermolecular forces produces fluids of high viscosity while weak intermolecular forces produces fluids of low viscosity.

Boiling point: is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Addition of heat results in the transformation of the liquid into its vapour without raising the temperature. Stronger intermolecular forces raises the boiling point of a liquid while weak intermolecular forces produces liquids of lower boiling point.

Surface tension: is the tension of the surface layer of a liquid caused by the attraction of the particles in the surface layer by the molecules in the interior of the liquid. Strong intermolecular forces produce a higher surface tension while weak intermolecular forces produce a lower surface tension.

Vapour pressure: is the pressure of a vapour in contact with its liquid or solid form. Strong intermolecular forces produce a lower rate of evaporation and a lower vapor pressure whreas, weak intermolecular forces produce a higher rate of evaporation and a higher vapor pressure.
