When freon is manufactured by tetrachloremethane, the reaction involved in this process is called
1 Sandmeyer reaction
2 Swarts reaction
3 Finkelstein reaction
4 All of these
Explanation:
Swarts reaction is used to prepare fluorides.Replacement of \({\mathrm{-\mathrm{Cl},-\mathrm{Br}}}\) from RX by -F is called swarts reaction. \({\mathrm{\mathrm{CCl}_{4}+2 \mathrm{HF} \xrightarrow{\mathrm{SbCl}_{5}} 2 \mathrm{HCl}+\mathrm{CCl}_{2} \mathrm{~F}_{2}}}\) (Freon)

2 \(\mathrm{CH}_{2} \mathrm{~F}_{2}\)
3 \(\mathrm{CCl}_{2} \mathrm{~F}_{2}\)
4 \(\mathrm{CF}_{4}\)

Assertion : Freons are extremely stable, low boiling non-flammable and non-corrosive compounds. Reason : Freons are used as refrigerant in refrigerators.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Freons are used as refrigerants because of their properties such as: meagre boiling point, low surface tension, and low viscosity. So option (2) is correct.
