Chlorofluorocarbons, CFCs, may be employed as refrigerants, aerosol propellants and fire extinguishers. CFCs such as $\text{CCl}_3\text{F}$ and $\text{CCl}_2\text{F}_2$ are more stable than chloroalkanes such as $\text{CCl}_4$. What causes their higher stability?
- AFluorine has a higher first ionisation energy than chlorine.
- BFluorine radicals are more stable than chlorine radicals.
- CThe C-F bond energy is larger than the C-Cl bond energy.
- DThe C-F bond is more polar than the C-Cl bond.
