Sodium tetrafluoroborate is an inorganic compound with formula NaBF 4.It is a salt that forms colorless or white rhombic crystals and is soluble in water (108 g/100 mL) but less soluble in organic solvents.
Despite the low reactivity of the tetrafluoroborate anion in general, BF − 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]
Battlefield is a video game series developed by DICE, and published by Electronic Arts.The series debuted with the Battlefield 1942.The games take place during historical events, an alternate history, and in the future.
Trimethyloxonium tetrafluoroborate is the organic compound with the formula [(CH 3) 3 O] + [BF 4] −. (It is sometimes called "Meerwein's salt" after Hans Meerwein. [1] [a]) This salt is a strong methylating agent, being a synthetic equivalent of CH + 3.
Battlefield is a military first-person shooter video game franchise primarily developed by Swedish company EA DICE and published by American company Electronic Arts.The series mainly focuses on online multiplayer, with gameplay taking place across large maps, and emphasizes teamwork and combined arms warfare.
Battlefield 4 is a 2013 first-person shooter video game developed by DICE and published by Electronic Arts.The game was released in October and November for Microsoft Windows, PlayStation 3, Xbox 360, PlayStation 4, and Xbox One, and is the sequel to 2011's Battlefield 3, taking place six years later during the fictional "War of 2020".
The acidity of fluoroboric acid is complicated by the fact that its name refers to a range of different compounds, e.g. [H(CH 3 CH 2) 2 O] + [BF 4] − (dimethyloxonium tetrafluoroborate), [H 3 O] + [BF 4] − (oxonium tetrafluoroborate), and HF·BF 3 (hydrogen fluoride-boron trifluoride 1:1 adduct) – each with a different acidity.
Although BF 4 − has high ionic mobility, solutions of its Li + salt are less conductive than other less associated salts. [2] As an electrolyte in lithium-ion batteries, LiBF 4 offers some advantages relative to the more common LiPF 6.
