In CF2Cl2 the stratospheric photolysis breaks a C-Cl bond and not a C-F bond. Taking C-Cl as about 340 kJ mol^-1 and C-F

Question

In CF2Cl2 the stratospheric photolysis breaks a C-Cl bond and not a C-F bond. Taking C-Cl as about 340 kJ mol^-1 and C-F as about 485 kJ mol^-1, the reason is that

Accepted Answer

the weaker C-Cl bond can be broken by the available UV photons while the stronger C-F bond cannot

Answer

fluorine atoms are larger than chlorine atoms

Answer

C-F bonds are non-polar

Answer

chlorine is more electronegative than fluorine

In $CF X_{2} Cl X_{2}$ the stratospheric photolysis breaks a C-Cl bond and not a C-F bond. Taking C-Cl as about $340 kJ mo l^{- 1}$ and C-F as about $485 kJ mo l^{- 1}$ , the reason is that
