Final answer:
Tetrafluoroethene forms the polymer polytetrafluoroethylene (PTFE), commonly known as Teflon, which is used as a non-stick coating on frypans. The, correct answer is D.
Step-by-step explanation:
The monomer tetrafluoroethene forms the polymer known as polytetrafluoroethylene (PTFE), which is commonly used for coating frypans. This polymer is better known by its brand name, Teflon, which was discovered by DuPont in 1938. Due to its highly inert and non-stick properties, PTFE is also used in a variety of other applications such as lubricants and electrical insulation for wires
