The chlorine molecules, cl2, would behave if mixed with water is best described by the polarity concept.
What is polarity?
Polarity is a phenomena by which the dissolving power of any molecule can be known if they are polar will completely dissociate in water and if non polar will partially dissociate in water
Here chlorine is very poorly dissolve in water due to its non polar nature and water is polar. Some compounds are polar for short time of period and attend a partially positive and a partially negative charge within them.
Therefore, Cl2 is a non polar compound describes the polarity.
