[{"from": "human", "value": "Please give me some details about this molecule. [C][=C][Branch1][C][Cl][Cl]"}, {"from": "gpt", "value": "The molecule appears as a clear colorless liquid with a chloroform-like odor. Flash point 0 \u00b0F. Boiling point 99 \u00b0F. Denser (at 10.1 lb / gal) than water and insoluble in water. Hence sinks in water. May polymerize exothermically if heated or contaminated. If the polymerization takes place inside a container, the container may rupture violently. Vapors heavier than air."}]
