Chemical formula. F 2 O Se: Molar mass: 132.967 g·mol −1 Appearance ... Seleninyl fluoride is an oxyfluoride of selenium with the chemical formula SeOF 2. Preparation
Selenium tetrafluoride (Se F 4) is an inorganic compound.It is a colourless liquid that reacts readily with water. It can be used as a fluorinating reagent in organic syntheses (fluorination of alcohols, carboxylic acids or carbonyl compounds) and has advantages over sulfur tetrafluoride in that milder conditions can be employed and it is a liquid rather than a gas.

Selenium is listed as an ingredient in many multivitamins and other dietary supplements, as well as in infant formula, and is a component of the antioxidant enzymes glutathione peroxidase and thioredoxin reductase (which indirectly reduce certain oxidized molecules in animals and some plants) as well as in three deiodinase enzymes. Selenium ...
All the alkali metals form monofluorides. All have the sodium chloride (rock salt) structure and are soluble in water and even some alcohols. [1] Because the fluoride anion is highly basic, many alkali metal fluorides form bifluorides with the formula MHF 2.
