Tetrafluoroethylene, Polytetrafluoroethylene, and Teflon (C2F4)
Tetrafluoroethylene (TFE) is the simplest alkene fluorocarbon. It is colourless, odorless and a gas at room temperature. It is unstable, tending towards decomposition to C and CF4, it also forms explosive peroxides in contact with air.
TFE can be polymerized to form polytetrafluoroethylene (PTFE), also known as Teflon. In the polymerization of TFE, the double bond between the carbons is broken thus leaving each carbon to readily bond to another atom. PTFE is hydrophobic which in conjunction with multiple other properties makes it highly useful in coatings for non-stick pans.
