Which of the following is Freon-11?

Options

A. `CCl_(3)F`
B. `CCl_(2)F_(2)`
C. `CClF_(3)`
D. `CF_(4)`

Answer

To determine which of the given options is Freon-11, we need to identify its chemical formula and characteristics. Freon-11 is also known as trichlorofluoromethane. Here’s a step-by-step breakdown of how to identify Freon-11:

### Step 1: Understand the Definition
Freon-11 is a chlorofluorocarbon (CFC) compound. It is specifically known as trichlorofluoromethane.

### Step 2: Identify the Chemical Formula
The chemical formula for Freon-11 is CCl3F. This indicates that it contains three chlorine (Cl) atoms, one fluorine (F) atom, and one carbon (C) atom.

### Step 3: Analyze the Given Options
If you are provided with multiple options, look for the one that matches the formula CCl3F. Other common Freon compounds include:
- Freon-12 (Dichlorodifluoromethane, CCl2F2)
- Freon-22 (Chlorodifluoromethane, CHClF2)

### Step 4: Confirm Characteristics
Freon-11 is colorless and odorless, and it was commonly used as a refrigerant and in aerosol products. However, it has been banned due to its role in ozone depletion.

### Conclusion
Freon-11 is identified as CCl3F, which is trichlorofluoromethane.
