Chemistry Question on Haloalkanes and Haloarenes
Which one is a reaction to prepare CCl2F2(freon-12) from CCl4?
A
Wurtz Reaction
B
Finkelstein
C
Elimination Reaction
D
Swartz Reaction
Answer
Wurtz Reaction
Explanation
Solution
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).
