Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Reactions with elemental fluorine are often sudden or explosive. Many substances that are generally regarded as unreactive, such as powdered steel, glass fragments, and asbestos fibers, are readily consumed by cold fluorine gas. Wood and even water burn with flames when subjected to a jet of fluorine, without the need for a spark. [12] [13]
The reaction mixture was warmed to 25°, 50 mL of water was added, and the lower organic layer was separated and dried with anhydrous magnesium sulfate and distilled to give 12.0 g (90%) of 1-fluorooctane as a colorless liquid, bp 42–43° (20 mm). 19 F NMR (CCl 3 F): -218.8 ppm (tt, 2 J = 49 Hz, 3 J = 25 Hz).

The 2021 FIA Formula One World Championship was a motor racing championship for Formula One cars which was the 72nd running of the Formula One World Championship.It is recognised by the Fédération Internationale de l'Automobile (FIA), the governing body of international motorsport, as the highest class of competition for open-wheel racing cars.
Fluorine gas (F 2) can act both as an electrophilic and atomic source of fluorine. [4] The weak F–F bond strength (36 kcal/mol (150 kJ/mol) [5]) allows for homolytic cleavage. The reaction of F 2 with organic compounds is, however, highly exothermic and can lead to non-selective fluorinations and C–C cleavage, as well as explosions. [6]
Aerial view of the Silverstone Circuit. The event, which was held over the weekend of 16–18 July, was the only Formula One race at Silverstone in 2021, [7] after the venue had held two races behind closed doors due to the COVID-19 pandemic in the United Kingdom during 2020; the 2020 British Grand Prix was won by Lewis Hamilton, while the other one-off race, the 70th Anniversary Grand Prix ...
The 2021 United States Grand Prix (officially known as the Formula 1 Aramco United States Grand Prix 2021) was a Formula One motor race, held on October 24, 2021, at the Circuit of the Americas in Austin, Texas, United States.
1,1,1,2-tetrafluorodisulfane, also known as 1,2-difluorodisulfane 1,1-difluoride or just difluorodisulfanedifluoride (FSSF 3) is an unstable molecular compound of fluorine and sulfur. The molecule has a pair of sulfur atoms, with one fluorine atom on one sulfur, and three fluorine atoms on the other.
