Unformatted text preview: 2. (a) CFCs have been implicated in ozone depletion. Show that when Freon 12 (CCl 2 F 2 ) is exposed to ultraviolet radiation, the compound decomposes to produce chlorine. (b) Draw the Lewis structure of Freon 12 and indicate the polarities of each bond within this compound. (c) Determine the percent ionic character of the C-Cl and C-F bonds. DATA: Average Bond Energies (kJ/mol) Single Bonds Multiple Bonds H–H 435 C=C 610 F–F 155 C ≡ C 836 Cl–Cl 242 C–C 347...
