May I leave it there?
The real problem with freon occurs when it is exposed to ultra violet light.
Freon converts to chlorine quite easily. What is so bad about that, you say... Good question!
Freon decomposes easily under the influence of light releasing solitary Chlorine atoms (not the Cl2 molecule)
CCl3F → CCl2F. + Cl.
The Chlorine atoms sit in the upper atmosphere for a long time. They do not react with Oxygen, but they do catalyse the conversion of Ozone O3 to Oxygen O2 (the stuff we breathe). Unfortunately, although Ozone is poisonous when breathed in, its blue colour screens the Earth from ultraviolet radiation from the sun. Without this protection, many organisms including ourselves are seriously harmed by solar UV.
No, freon is stable matter and unreactable with oxygen in room temperature, except with ozone (O3)
"Freon" is a trade name and a colloquial term for a whole class of refrigerants made by Dupont. They have different chemical makeups.
