Question

consider the data for the following liquids with similar molar masses at the same temperature. predict which liquid has the strongest intermolecular attraction based on viscosity data. ethyl ether (viscosity = 0.23 centipoise) propionic acid (viscosity = 1.10 centipoise) propyl chloride (viscosity = 0.35 centipoise) ethyl formate (viscosity = 0.40 centipoise) butyl alcohol (viscosity = 2.95 centipoise)

Explanation:

Viscosity is related to intermolecular forces: higher viscosity means stronger intermolecular attractions (since more attraction resists flow). Among the options, butyl alcohol has the highest viscosity (2.95 centipoise), so it has the strongest intermolecular attraction.

Answer:

butyl alcohol (viscosity = 2.95 centipoise)
