WebIn the simpler molecule poly (ethene) the carbon backbone of the molecule just has hydrogen atoms attached to it, and the chain is very flexible - it definitely isn't a straight molecule. However, in PTFE, the fluorine atoms in one CF 2 group are big enough to interfere with those on the neighbouring groups. WebMar 20, 2024 · Tetrafluoroethylene (C 2 F 4 ), a colourless, odourless gas, is made by heating chlorodifluoromethane (CHClF 2) in the range of 600–700 °C (1,100–1,300 °F). Chlorodifluoromethane in turn is obtained by reacting hydrogen fluoride (HF) with chloroform (CHCl 3 ).

http://passmyexams.co.uk/GCSE/chemistry/alkenes-and-halogens-reaction.html WebEthylene Tetrafluoroethylene (ETFE) is a melt processable, fluorine-based plastic designed to have high corrosion resistance and strength over a wide temperature range. The crystallinity of ETFE ranges from 40-60%. The mechanical properties of ETFE are superior to those of PTFE and FEP but it is less flexible than PTFE.

WebCombined with hydrogen, fluorine makes hydrofluoric acid, an acid so powerful that it is used to etch glass. Perhaps fluorine’s most potent threat though, comes from its use in compounds that can be handled with little to no risk. Fluorine is used to create chlorofluorocarbons, known as CFC’s. Web2. Substitution Reactions – breaking of a C-H bond in an alkane or an aromatic ring and replacing it with another atom or group of atoms Usually occur slowly at room temperature, so light may be necessary as a catalyst Often substitutes a halogen for a hydrogen No change in saturation Propane contains hydrogen atoms bonded to end carbons and the …
