pentafluoroeteeni

Pentafluoroethene is a chemical compound with the formula C2F5H. It is a halogenated alkene, meaning it contains both carbon-carbon double bonds and halogen atoms, specifically fluorine, along with a hydrogen atom. It is a colorless gas at room temperature and pressure. Its structure consists of a two-carbon chain with a double bond between the carbons. One carbon atom is bonded to two fluorine atoms and one hydrogen atom, while the other carbon atom is bonded to three fluorine atoms.

Pentafluoroethene is a relatively stable compound due to the strength of the carbon-fluorine bonds. It can participate in addition reactions across the double bond, typical of alkenes, but the presence of fluorine atoms influences its reactivity. It is often produced as a byproduct in the synthesis of other fluorocarbons. Its applications are limited, but it has been investigated for use as a refrigerant or as a component in specialized chemical processes. Due to its fluorinated nature, it is considered a greenhouse gas.
