उत्तर
CFCs : (Chlorofluorocarbons) are organic compounds that contain carbon, chlorine, fluorine produced as volatile derivatives of methane and ethane which catalyze the conversion of ozone (O3) into O2, while O3 is more powerful to absorb ultra-violet rays than that of O2. So CFCs disturb the ozone layer which is so essential for the earth.
