Question

Which class of carbon compounds are responsible for the depletion of the ozone layer at the higher level of the atmosphere?

Answer 1

Hint: The synthetic chemicals, chlorofluorocarbons consisting of halogens as a free radical are mainly responsible for the ozone layer depletion.

Complete answer:
Chlorofluorocarbon compounds mainly known as CFCs are responsible for the ozone layer depletion at the higher level of atmosphere. CFCs usually at altitudes higher releases chlorine in the presence of UV light which causes depletion and hazard to the ozone layer.
The chlorine reacts with the ozone layer to convert into an oxygen molecule, thus destroying the layers of ozone.

Additional information:
Chlorofluorocarbons are the halogenated hydrocarbons usually consisting of carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), mainly produce a volatile material of methane, ethane, and propane. Many CFCs products are used in our daily lives such as in refrigerants, in aerosols and other solvents. The usage of these products also leads to ozone layer depletion.

Note: Reactions in the atmosphere is a photo induced reaction of carbon and chlorine bond. As the chlorine atom reacts with CFCs to form chlorine radical which is long lived radical in the atmosphere, and where it catalyzes the conversion of ozone into oxygen. Hence CFCs are the chemicals that destroy the earth's precious and protective layer.

Solve this question by keeping a group of carbon compounds, halogen, into your mind as free radicals like bromine and chlorine are always hazardous to the earth. Take the idea of ozone layer depletion first, from which substances the ozone layer is made up of and how it protects us from depletion.
