Question

Which of the following compounds is an example of Freon?

• A. C₂Cl₂F₂
• B. C₂HF₃
• C. C₂F₄
• D. C₂H₂F₂

Answer 1

The Correct Option is A

The question tests your knowledge of Freon compounds. Freons are a class of compounds that are primarily chlorofluorocarbons (CFCs) containing carbon, chlorine, and fluorine. They are used extensively as refrigerants, propellants, and solvents. One of the widely known Freons is Freon-12.

Let's analyze the given options to determine which compound is a Freon:

1. Option 1: C_2Cl_2F_2
   This compound contains both chlorine (Cl) and fluorine (F) atoms. It matches the typical composition of Freons (CFCs) and is indeed a well-known Freon called Freon-114.
2. Option 2: C_2HF_3
   This compound contains hydrogen (H) in addition to carbon and fluorine but lacks chlorine atoms. It represents a type of hydrofluorocarbon (HFC), not a traditional Freon.
3. Option 3: C_2F_4
   This compound consists only of carbon and fluorine, making it a perfluorocarbon (PFC). It does not contain chlorine, and thus, it is not a Freon.
4. Option 4: C_2H_2F_2
   This compound has hydrogen and fluorine in addition to carbon but lacks chlorine, categorizing it under hydrofluorocarbons (HFCs) and not a CFC like Freon.

Only Option 1, C_2Cl_2F_2, fits the description of a Freon, as it contains the necessary chlorine and fluorine atoms in its structure, making it a chlorofluorocarbon.

Therefore, the correct answer is C_2Cl_2F_2, also known as Freon-114.
