The first step is the dissociation of the chlorine atom:

The oxygen then pushes aside the chlorine atoms, leaving almost no room for the lead to occupy.

The chlorine atoms within them are released and directly attack ozone.

A single chlorine atom can destroy over one hundred thousand ozone molecules.

Furthermore, a single chlorine atom is able to react with 100,000 ozone molecules.

The rest of the unaccounted carbon bonds are occupied by chlorine atoms.

The ten chlorine atoms define a pair of octahedra that share a common edge.

Contamination is predominantly of the type with 2 or 3 chlorine atoms.

Remaining bonds not accounted for are occupied by chlorine atoms.

Moving the chlorine atom around the ring reduces the potency significantly.
