[{"from": "human", "value": "Could you provide a description of this molecule? [C][C][Branch1][C][F][Branch1][C][F][F]"}, {"from": "gpt", "value": "The molecule is a colorless, highly flammable gas. It is heavier than air and vapors may travel from a leaking container to a source of ignition causing a flame to flashback to the container. Contact with the unconfined liquid can cause frostbite. Under prolonged exposure to fire or heat the containers may rupture violently and rocket."}]
