No, they are not. CFC's destroy the ozone layer.
Many countries are destroying the ozone. The developed nations are on top.
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, and methyl bromide are chemicals that are known to be dangerous to the ozone layer. These substances contain chlorine and bromine atoms that can break down ozone molecules when released into the atmosphere.
In the stratosphere, the temperature increases with height. This is due to the presence of the ozone layer near the top of the stratosphere. The ozone layer absorbs incoming UV radiation, and thus the temperatures are warmer at the top of the stratosphere than at the bottom.
You can create a simple 3D model of the Earth using a cardboard sphere and blue paper to represent the atmosphere. Then, cut a hole in the ozone layer location on the model to demonstrate its depletion. You can also use green paper strips to represent harmful gases like CFCs that contribute to ozone depletion.
The ozone layer is a few miles / kilometers thick, and has variable concentration with lower values at "top" and "bottom". It cannot have a hard "distance" without nuance in meaning. The Earth's radius at the poles is 6356.8 km, and at the equator 6378.1 km. The ozone layer starts about 10 km above this at the equator, and less than this near the poles. So it starts about 6388.1 km, and ends about 6428.1 km near the equator. 10-50 km + 6378 km near the equator.
That would be the 2nd layer, the stratosphere layer with the ozone at top.
The ozone layer is located in the top layer of the stratosphere
It is on the bottom. It is pool of ozone molecules.

The "ozone" layer at the top of the atmosphere.

Various culprits are there. CFC's are on the top.

The stratosphere extends from about 11 kilometers to 50 kilometers above the Earth's surface. This layer contains the ozone layer, which absorbs and scatters the sun's ultraviolet radiation. Temperature increases with altitude in the stratosphere due to the absorption of UV radiation by the ozone layer.
