Some important organofluorine compounds. A: fluoromethane B: isoflurane C: a CFC D: an HFC E: triflic acid F: Teflon G: PFOS H: fluorouracil I: fluoxetine Organofluorine chemistry describes the chemistry of organofluorine compounds, organic compounds that contain a carbon–fluorine bond.
Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...

This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...

trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze(E), R-1234ze(E)) is a hydrofluoroolefin.It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a, as a blowing agent for foam and aerosol applications, and in air horns and gas dusters. [3]
[2] [3] The American chemist Richard F. Heck was a long-time resident in the Philippines when he was awarded the 2010 Nobel Prize in Chemistry. [ 4 ] [ 5 ] Before Ressa's win, Filipinos speculated multiple times when and who will be the first to win from their country. [ 6 ]
Many organochlorine compounds have been isolated from natural sources ranging from bacteria to humans. [3] [4] Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.
