A chemical used in refrigerators and air conditioners and is a source of Cl− is __________.
Open in App
Solution
The correct option is D Freon
The freons are
simple fluorinated and aliphatic organic compounds that contain
fluorine, carbon, hydrogen, chlorine, bromine etc. These are used as
the refrigerants and propellants. Chlorofluorocarbons,
Hydrochlorofluorocarbons are the types of freons. They have a low
boiling point and low suface tension due to which they are used in
refrigerators, air conditioners etc. However, they undergo
photo-dissociation when exposed to the UV rays, releasing a reactive
chlorine ion that is capable of reacting with ozone. This reaction is
responsible for the depletion of the ozone in the stratosphere. Hence, the correct
answer is 'Freon'.
