Fluorine's chemistry is dominated by its strong tendency to gain an electron. It is the most electronegative element and elemental fluorine is a strong oxidant. The removal of an electron from a fluorine atom requires so much energy that no known reagents are known to oxidize fluorine to any positive oxidation state. [20]
Fluorine is a chemical element; it has symbol F and atomic number 9. It is the lightest halogen [note 1] and exists at standard conditions as pale yellow diatomic gas. Fluorine is extremely reactive as it reacts with all other elements except for the light inert gases. It is highly toxic.
Fluorine, in the form of fluoride, is considered to be a micronutrient for human health, necessary to prevent dental cavities, and to promote healthy bone growth. [28] The tea plant (Camellia sinensis L.) is a known accumulator of fluorine compounds, released upon forming infusions such as the common beverage. The fluorine compounds decompose ...
Fluorine is often added to drug molecules during drug design, as even a single atom can greatly change the chemical properties of the molecule in desirable ways. Because of the considerable stability of the carbon–fluorine bond , many drugs are fluorinated to delay their metabolism , which is the chemical process in which the drugs are turned ...
It can be seen as a similar chemical compound to methanol where every hydrogen atom is replaced by a fluorine atom. It is a trifluoromethyl ester of hypofluorous acid. It is prepared by the reaction of fluorine gas with carbon monoxide: 2 F 2 + CO → CF 3 OF. The gas hydrolyzes only slowly at neutral pH.
It is a compound based on acetamide with one fluorine atom replacing hydrogen on the methyl group. It is very toxic. [1] It is a metabolic poison which disrupts the citric acid cycle and was used as a rodenticide. [2] May cause reproductive disorders. If swallowed or in contact with skin, it can cause serious damage and death. Can cause serious ...
The molecular shape has five fluorine and one oxygen atom arranged around a sulfur atom in an octahedral arrangement. Another fluorine atom is attached to the oxygen in almost a straight line with the S-O connection. So the molecular formula can also be written as SF 5 OF. The average S-F distance is 1.53 Å. The angles ∠FSF and ∠FSO are 90 ...
4 serves as a fluorine source to deliver an equivalent of fluoride. [2] The Balz–Schiemann reaction for the synthesis of aryl fluorides is the best known example of such a reaction. [3] Ether and halopyridine adducts of HBF 4 have been reported to be effective reagents for the hydrofluorination of alkynes. [4]
