What common characteristic do Freon-12 and methyl chloride share?

Freon-12 and methyl chloride are both chlorinated compounds, which means they each contain chlorine in their molecular structure. This commonality is significant as it influences their chemical properties and behaviors.

Freon-12, also known as dichlorodifluoromethane, is a halocarbon primarily used as a refrigerant. Methyl chloride, or chloromethane, is used as a solvent and in chemical synthesis. While both compounds exhibit different physical characteristics such as boiling points and vapor densities, the presence of chlorine in both of their structures is the notable shared aspect.

The other characteristics listed do not apply to both Freon-12 and methyl chloride. For instance, while methyl chloride is flammable, Freon-12 is not. This differentiates their safety profiles and their handling requirements.
