Gas A is unreactive, non-toxic, non-flammable, reaches the stratosphere, and dissociates under UV radiation. What are the initial intermediates?
1. \(\dot{\mathrm{C}} \mathrm{FCl}_2+\dot{\mathrm{C}} \mathrm{H}_3\)
2. \(\dot{\mathrm{C}} \mathrm{l}+\dot{\mathrm{C}} \mathrm{F}_2 \mathrm{Cl}\)
3. \(\dot{\mathrm{C}} \mathrm{H}_3+\dot{\mathrm{C}} \mathrm{F}_2 \mathrm{Cl}\)
4. \(\mathrm{Cl} \dot{\mathrm{O}}+\dot{\mathrm{C}} \mathrm{F}_2 \mathrm{Cl}\)
