CFC molecules are the most harmful kind of molecules. They are synthesized by Chlorine and Fluorine. What they do is react with ozone and decompose to destroy it.
The real problem isn't molecules, it's halogen free radicals. A chlorine free radical (basically, a chlorine atom not bonded to anything else) is highly reactive and will react catalytically with ozone to break it down (the net equation is Cl. + 2O3 -> Cl. + 3O2; the dot next to the Cl represents an unpaired electron).
Chlorofluorocarbons are prone to producing chlorine free radicals in a UV-rich environment (such as the upper atmosphere, where there is far more UV radiation than down lower), so it's possible that "CFCs" is the answer you were looking for.

The main molecules destroying ozone are CFC's. They decompose the ozone molecules.
CFC's are destroying the ozone layer. They react with ozone and deplete it.
The stratosphere consists of a layer of ozone molecules. These molecules form a layer known as ozone layer.
Many countries are destroying the ozone. The developed nations are on top.
Ozone molecules live in the ozone molecules. Ozone layer is a large pool of ozone molecules which protect us from harmful UV radiations of the sun.
The main molecules destroying ozone are CFC's. They decompose the ozone molecules.
CFC's are destroying the ozone layer. They react with ozone and deplete it.
Stratospheric ozone forms the ozone layer. Destroying it is ozone depletion.
CFC's are destroying the ozone layer. They can also harm our health.
We are destroying ozone layer. It is because of the use of CFC's.
CFC's are destroying our ozone layer. These CFC's are one of the most harmful chemicals of the environment.
Carbon dioxide, CO2, has very little to do with the ozone layer. The ozone layer will repair itself if we stop damaging it, which we have, by banning CFCs, chlorofluorocarbon gases, the chlorine of which was destroying the ozone molecules. Scientists hope the ozone layer will be completely restored by 2060.
The CFC molecules affect ozone layer. These molecules react with ozone to deplete it.
Ozone layer depletion is the death of ozone molecules. These molecules reside in the ozone layer.
