Which of the following is Freon-11?

Options

A. `C Cl_(3)F`
B. `C Cl_(2)F_(2)`
C. `C ClF_(3)`
D. `CF_(4)`

Answer

To determine which of the given compounds is Freon-11, we can follow these steps:

### Step 1: Understand what Freon is
Freons are chlorofluorocarbons (CFCs) derived from methane (CH4) and ethane (C2H6). They are primarily used as refrigerants and propellants.

**Hint:** Remember that Freons are a class of compounds known as chlorofluorocarbons.

### Step 2: Identify the chemical formula of Freon-11
Freon-11 is specifically known as trichlorofluoromethane. Its chemical formula is CCl3F.

**Hint:** Look for the name "trichlorofluoromethane" to find the corresponding formula.

### Step 3: Analyze the options provided
The options given are:
1. CCl3F
2. CCl2F2
3. CClF3
4. CF4

We need to identify which of these corresponds to Freon-11 (CCl3F).

**Hint:** Compare each option's formula with the known formula of Freon-11 (CCl3F).

### Step 4: Match the formula
- **CCl3F**: This matches the formula for Freon-11.
- **CCl2F2**: This is Freon-12.
- **CClF3**: This is Freon-13.
- **CF4**: This is Freon-14.

**Hint:** Identify the specific formula that matches CCl3F.

### Step 5: Conclusion
The compound that corresponds to Freon-11 is **CCl3F**.

**Final Answer:** Freon-11 is **CCl3F**.
