Clorofluorocarbonos

The video discusses halogenated compounds like ethane, methane, and propane, where hydrogen atoms are replaced by chlorine and fluorine. These compounds have historically been used in refrigerators, fire extinguishers, and aerosols. However, their use has significantly harmed the ozone layer, leading to an international agreement in 1989 to phase them out gradually.
