Why Are Oxygenates Useful in Preventing Ozone Formation?
Chemistry of Ozone Formation Ozone Forms Readily in the Stratosphere as Incoming Ultraviolet Radiation Breaks Molecular Oxygen (Two Atoms) into Atomic Oxygen...
Why is Cl important for ozone destruction?
Chemistry of Ozone Depletion
Chlorine is able to destroy so much of the ozone because it acts as a catalyst. Chlorine initiates the breakdown of ozone and combines with a freed oxygen to create two oxygen molecules. After each reaction, chlorine begins the destructive cycle again with another ozone molecule.
How do CFCs affect the ozone layer?
Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules.
