"WebEvidence that chlorine is causing the ozone depletion: According to the hypothesis, when CFCs break down they produce chlorine, which destroys ozone and generates chlorine monoxide. So scientists reasoned that if these reactions were occurring, ozone levels should be low where chlorine monoxide levels are high and vice versa. " - How does chlorine monoxide breakdown ozone

Free chlorine atoms and chlorine-containing gases, such as chlorine monoxide (ClO), could then … WebOne chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created. Some compounds release chlorine and bromine on exposure to high ultraviolet light, which then contributes to ozone layer depletion. Such compounds are known as Ozone Depleting Substances (ODS).

WebAug 25, 2016 · Yes - CFCs interact with and break down ozone. CFCs are lifted by buoyancy into the stratosphere, where they are broken up by the sun's ultraviolet radiation (1), and the chlorine then reacts with ozone (2), with equation: Then that chlorine monoxide reacts with atmospheric oxygen: (4) and so the chlorine can go on to damage more ozone, again ... WebHow do CFCs destroy ozone? When the molecule of chlorine monoxide (ClO) meets another molecule of oxygen (O) it breaks up, releasing chlorine (Cl), which can “destroy” another molecule of ozone (O3), creating the catalytic cycle of chlorine.
