It's a synthetic organic substance that doesn't exist in nature. It's a man-made gas.
They are halogenated hydrocarbons that contain carbon, hydrogen, chlorine, and fluorine and are created as volatile derivatives of methane, ethane, and propane.
Chlorofluorocarbons are employed in a variety of applications due to their low toxicity, reactivity, and flammability for example in refrigerators, air conditioners, and aerosol spray.
It is another gas that contributes to the greenhouse impact. Because of its damaging reactions with ozone particles, which protect the earth from UV light, it is highly harmful.
Due to their negative impacts the use of CFCs is reduced.
Therefore, Chlorofluorocarbons are composed of Carbon, Fluorine, Chlorine, and Hydrogen.
