C2H4F2, also known as 1,1-Difluoroethane, is a chemical compound that consists of two carbon atoms, four hydrogen atoms, and two fluorine atoms. It is a colorless gas at room temperature and is often used as a refrigerant and in the production of various fluorinated compounds. Its molecular structure features a double bond between the carbon atoms, contributing to its reactivity. This compound is part of a larger group of chemicals known as hydrofluorocarbons (HFCs), which are commonly used in refrigeration and air conditioning systems. Due to its properties, C2H4F2 is considered a potential alternative to ozone-depleting substances, making it relevant in discussions about environmental impact and climate change.
