Freons, chlorofluoro compounds of methane and ethane are stable, low boiling, non-toxic, non-inflammable and non-reactive compounds. These are extensively used in refrigerators and air conditioners. These are also used as propellants for aerosols and foams to spray out deodorants, cleansers, shaving creams and hair sprays. However, its use has been discouraged and restricted in some countries. As a student of science, What is freon-12? How is it prepared?
