Haloalkanes And Haloarenes

The correct answer is option (A): Wurtz Reaction
Wutz reaction is a method for the formation of CCl₂F₂ from CCl₄CCl₂ will be formed as an intermediate, and upon further reaction with fluorine, dichlorodifluoromethane will be formed. When CCl₄ will react with a strong base, a Chloride ion will be removed from CCl₄ and thus form CCl₂. Later CCl₂ will react with fluorine to form CCl₂F₂. Wurtz reaction, which converts aldehydes and ketones into olefins (alkenes).

Step 1: Understanding the Reaction.
The question asks for the correct reagent to carry out the reaction involving an alkyl halide. In this case, we need to identify the correct reagent for substitution or other transformations.
Step 2: Analyzing the Options.
- (A) is not the correct reagent for alkyl halide substitution.
- (B) Alkyl Iodide is the correct answer as sodium iodide is used for substitution reactions.
- (C) is used in other types of reactions like nucleophilic substitution but is not the best choice here.
- (D) is not commonly used in this type of reaction.
Step 3: Conclusion.
The correct answer is (B) Alkyl Iodide as it is the appropriate reagent for this substitution reaction.
