You accidentally spilled an unknown liquid on a lab bench. It spreads out across the lab bench and quickly evaporates. What can you infer about the structure of the molecules? Explain your reasoning.

That the particles have mostly non-polar structures or, have a very low degree of electronegativity (i.e. very low or no attractive interactions) so that particle - particle interaction favors the gas phase when not in an equilibrium based environment. That is, a closed container of liquid were liquid phase is in equilibrium with gas phase. However, when not in a closed container; i.e., spilled, particles evaporate rapidly moving into the gas phase from liquid phase.

Hope this helps. :-)

The molecule of the liquid which quickly evaporates means that it has a non

polar structure.

Polar substances have the presence of regions of positive and negative

charges in them which makes them more stable. Non polar compounds on

other hand have charges distributed in a spherically symmetric manner.

Non polar substances are less stable and have very low boiling points and

is the reason the liquid quickly evaporated when it was spilled.
