Group Title
Chlorofluorocarbons (CFC's) are organic compounds that have been implicated in ozone depletion. When the CFC known as Freon 12 (CCl2F2) is exposed to UV radiation (wavelength in the range of 10 nm to 400 nm, a bit shorter than visible light), a chlorine atom breaks off from the rest of the molecule. Prove that this is possible by calculating the maximum wavelength (in meters) capable of breaking the CCl bond.

You have the enthalpies of the CC bond and the ClCl bond, both of which are homonuclear. To find the heteronuclear bond enthalpy, CCl, you have you use the formula Professor Cima showed in the lecture. It is the geometric mean of the two homonuclear enthalpies + 96.3(difference of the two electronegativities)^2 ext, use E = ħc / λ where E = energy per photon ħ = plancks constant = 6.626x10^34 J s c = speed of light = 3.00x10^8 m/s λ = wavelength.. E = ħc / λ rearranging λ = ħc / E for CCl... λ = (6.626x10^34 J s) x (3.00x10^8 m/s) / (5.63x10^19 J) = 3.53x10^7 m = 353x10^9 m = 353 nm
