Question

What are X and Y in the reaction?
\[C{F_2}C{l_2}\xrightarrow{{UV}}X + Y\]
A) \[ClC{F_2}^.,C{l^.}\]
B) \[{C_2}{F_4},C{l_2}\]
C) \[CFC{l_2}^.,{F^.}\]
D) \[_.^.CC{l_2},{F_2}\]

Answer 1

Hint: We must have to know that the dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halo methane (CFC) used as a refrigerant and aerosol spray propellant. . Dichlorodifluoromethane appears as a colorless gas having a faint ethereal odor.

Complete answer:
We have to know that the use of Dichlorodifluoromethane is the only allowed usage as fire retardant in submarines and aircraft. It is soluble in many organic solvents. Dichlorodifluoromethane was one of the original propellants for Silly String. R-12 cylinders are colored white. The presence of chlorofluorocarbons in the stratosphere can catalyze the destruction of ozone. UV light causes a chlorine free radical to be released.
\[C{F_2}C{l_2}\xrightarrow{{UV}}ClC{F_2}^.{\text{ + }}C{l^.}\]
Halocarbon compound used in air conditioning systems as a refrigerant. One of two primary chlorofluorocarbons that photolysis at high altitudes to release chlorine atoms, it is an important factor in ozone depletion. Dichlorodifluoromethane appears as a colorless gas having a faint ethereal odor. Dichlorodifluoromethane appears as a colorless gas having a faint ethereal odor. This compound is shipped as a liquid confined under its own vapor pressure. Contact with the unconfined liquid can cause frostbite. Both components are noncombustible; it can asphyxiate by the displacement of air. Exposure of the closed container to prolonged heat or fire can cause it to rupture violently and rocket.

Option A is the correct answer.

Note:
We need to remember that the R-12 was used in most refrigeration and vehicle air conditioning applications prior to 1994 before being replaced by \[1,1,1,2 - \]tetrafluoroethane (R-134a), which has an insignificant ozone depletion potential. Automobile manufacturers started using R-134a instead of R-12 .
