What is the chemical formula for Freon?

The chemical formula for Freon, specifically the most common type known as dichlorodifluoromethane, is represented by the formula CCl2F2. This compound belongs to a class of chemicals known as chlorofluorocarbons (CFCs), which have been widely used as refrigerants, propellants in aerosol applications, and in foam-blowing agents.

The significance of the components in the formula CCl2F2 is as follows: it contains two chlorine (Cl) atoms, two fluorine (F) atoms, and one carbon (C) atom. The presence of fluorine and chlorine is critical to understanding Freon's properties and its historical use, as these halogens have low reactivity and make the compound stable under a variety of conditions, which is why it was favored for applications involving cooling and refrigeration.

In the context of the other choices, each of those represents different chemical compounds with varying structures and uses, but only CCl2F2 specifically denotes the most commonly recognized type of Freon.
