Question

The chemical name of freon is
A) Dichlorofluoromethane
B) Trichlorotrifluoroethane
C) Dichlorofluorine
D) Dichlorodifluoromethane

Answer 1

Hint: Freon is a chlorofluorocarbon (CFC). Freon is in the form of liquid or gas. Freons are unscented, non-flammable and non-corrosive in nature and have low toxicity. Freons are used as fuels for aerosol spray propellants are used in specialized applications. Freon is generally used as a refrigerant.

 Complete step by step answer:
We know that freon is a chlorofluorocarbon (CFC).
Freons are simple fluorinated aliphatic organic compounds which are used in industries. Freons contain fluorine and carbon along with hydrogen, chlorine and bromine.
Freons are unscented, non-flammable and non-corrosive in nature and have low toxicity. Freons have low boiling points, low surface tension and low viscosity. Thus, freons are used as refrigerants.
Freons are used as fire retardants in submarines and aircrafts. Also, freons are used as fuels for aerosol spray propellants are used in specialized applications. Freons are soluble in many organic solvents.
Freons are highly stable inert compounds. As they are non-flammable they do not have any fire hazards. Freons do not give a detectable odour in their circulation through refrigeration and air conditioners.
The chemical formula for freon is $\text{CC}{\text{l}}_{\text{2}}{\text{F}}_{\text{2}}$. Thus, the chemical name of freon is dichlorodifluoromethane.
Thus, the correct option is (D) dichlorodifluoromethane.

Note:Freons are harmful to the environment and the climate. Freons exhaust the ozone layer of the earth. The photochemical dissociation of freons causes degradation of the ozone layer. Degradation of ozone can lead to the exposure of humans to the ultraviolet radiation which results in skin cancer. Thus, use of freons has been banned in many countries.
