But there are others, including methane, nitrous oxide—and chlorofluorocarbons (CFCs). CFCs were developed in the late 1920s to replace toxic compounds used in refrigeration and air conditioning; they have also been used in … coach sportif decathlon Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane. The most common representative is dichlorodifluoromethane (R-12). … See more As in simpler alkanes, carbon in the CFCs bond with tetrahedral symmetry. Because the fluorine and chlorine atoms differ greatly in size and effective charge from hydrogen and from each other, the methane-derived … See more The most important reaction of the CFCs is the photo-induced scission of a C-Cl bond: CCl3F → CCl2F + Cl The chlorine atom, written often as Cl , behaves very differently from the chlorine molecule (Cl2). The … See more Carbon tetrachloride (CCl4) was used in fire extinguishers and glass "anti-fire grenades" from the late nineteenth century until around the end of World War II. Experimentation with chloroalkanes for fire suppression on military aircraft began at least as early as … See more CFCs and HCFCs are used in various applications because of their low toxicity, reactivity and flammability. Every permutation of … See more • Chlorofluorocarbons (CFCs): when derived from methane and ethane these compounds have the formulae CClmF4−m and C2ClmF6−m, where m is nonzero. • Hydro … See more CFCs were phased out via the Montreal Protocol due to their part in ozone depletion. The atmospheric … See more Because the time history of CFC concentrations in the atmosphere is relatively well known, they have provided an important constraint on ocean circulation.
