Freon 12 is manufactured from which of the following compound in the Swart's reaction?

Options

A. Dichloromethane
B. Trichloromethane
C. Tetrachloromethane
D. Dichlorodifluoromethane

Explanation

To solve the question regarding the manufacturing of Freon 12 in the Swartz reaction, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Freon 12**:
Freon 12 is chemically known as dichlorodifluoromethane, with the formula CCl2F2.

2. **Understand the Swartz Reaction**:
The Swartz reaction is a process used to synthesize fluorinated hydrocarbons. It typically involves the reaction of a chlorinated compound with a fluoride source in the presence of a catalyst.

3. **Identify the Starting Compound**:
In the context of the Swartz reaction, Freon 12 is manufactured from carbon tetrachloride (CCl4), also known as tetrachloromethane.

4. **Write the Reaction**:
The reaction can be summarized as follows:
- 3 moles of CCl4 react with 2 moles of antimony fluoride (SbF5) in the presence of antimony pentachloride (SbCl5).
- The products of this reaction include Freon 12 (CCl2F2) and antimony trichloride (SbCl3).

5. **Conclusion**:
Therefore, the correct answer to the question is that Freon 12 is manufactured from carbon tetrachloride (CCl4) in the Swartz reaction.

### Final Answer:
Freon 12 is manufactured from carbon tetrachloride (CCl4) in the Swartz reaction.
