WebHFC refrigerants contain no chlorine atoms, and thus, they have no ozone-depleting potential (ODP). However, HFC refrigerants typically have a high global warming … Webit, the carbon atom still requires more bonds to reach the required four, those bonds will be to chlorine atoms. So far, the one carbon atom of CFC-12 has only formed two bonds, both with fluorine atoms. Thus the remaining two bonds must be chlorine atoms. Therefore, CFC-11's chemical formula is CCl 3 F. WebRefrigerants are divided into groups according to their chemical composition. Following the discovery that some of these chemical compounds may be harmful to the environment, they are being replaced with more environmentally friendly alternatives (see Figure 5.2).The process is not easy, and although there are alternatives to old refrigerants, the new … famu alma mater words
