Question

Freon group of refrigerants are
A) Inflammable
B) Toxic
C) Non-Flammable and toxic
D) Non Toxic and non-In flammable

Answer 1

Hint : Freons are considered as refrigerants because of their properties such as: meagre boiling point, low surface tension, and low viscosity. Also they are incredibly stable and inert substances which are used as refrigerants. Some examples of the Freon group of refrigerants are Dichlorodifluoromethane (Freon $12$ ) , trichlorofluoromethane (Freon $11$ ), dichlorotetrafluoroethane (Freon $114$ ), etc.

Complete Step By Step Answer:
A refrigerant is a chemical substance (generally a liquid), which is used in the refrigeration cycle to cool the space in refrigerators.
Freon gas is an odourless, colourless, non-inflammable, non-corrosive in nature which began to be used as refrigerants in $1930s$ . Freons consist of simple fluorinated aliphatic organic compounds. Freons also include hydrogen, bromine or chlorine.
Some examples of the Freon group of refrigerants are Dichlorodifluoromethane (Freon $12$ ) , trichlorofluoromethane (Freon $11$ ), dichlorotetrafluoroethane (Freon $114$ ), etc.
Freons are used as refrigerants because of their properties such as: meagre boiling point, low surface tension, and low viscosity. They are also inert and highly stable in nature.
Therefore, we can say that they are non-Inflammable and non-toxic.
But if it is deeply inhaled, it can cause health problems.
Hence, option D) Non Toxic and non-In flammable is correct.

Note :
There are many applications of Freons such as, they are used in refrigerators, air conditioning systems, foam blowing agents, solvents, polymer intermediates, etc.Ozone layer is a thin layer present in the stratosphere, which protects us from the harmful radiation (ultraviolet radiations) coming from the sun.
The chlorofluorocarbons (CFCs) are very harmful for the environment as well as human beings as when they are released into the atmosphere, they react with gases present in the stratosphere and release chlorine free radicals which then cause the depletion of the ozone layer.
