Photons with wavelength <240 nm are needed to break the C-Cl bond in CCl2F2. This wavelength is less that what you should have calculated for the wavelength that corresponds to the energy of a C-Cl bond. What else matters in determining if a photon with a given wavelength of light can break a bond in a given molecule?
