Correct option is B
Sol.
Correct Ans is (B) Swarts reaction
Explanation:
Freon-12 (also known as dichlorodifluoromethane, CCl₂F₂) is most commonly manufactured by the Swarts reaction, which is a fluorination reaction. In this process, a metal halide (usually Aluminum chloride) is used to substitute chlorine atoms in carbon tetrachloride (CCl₄) with fluorine atoms, producing Freon-12.
Information Booster:
- Swarts reaction involves the substitution of chlorine with fluorine, often using a fluorine-containing compound like HF or SbF₅.
- The Swarts reaction is crucial in producing various halogenated compounds, including refrigerants and propellants like Freon-12.
Additional Information:
- (A) Wurtz reaction: This is a coupling reaction of alkyl halides with sodium to form alkanes, and it does not relate to the production of Freon-12.
- (C) Elimination reaction: This type of reaction involves the removal of a small molecule (like water or hydrogen halide) from a substrate and is not related to Freon-12 synthesis.
- (D) Substitution reaction: While Swarts reaction is a substitution reaction, the term substitution reaction is too broad, and Swarts specifically refers to the fluorination process used in making Freon-12.
