翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Phosphorus halide ： ウィキペディア英語版 Phosphorus halide There are three series of binary phosphorus halides, containing phosphorus in the oxidation states +5, +3 and +2. All compounds have been described, in varying degrees of detail, although serious doubts have been cast on the existence of PI5.〔I. Tornieporth-Getting & T. Klapötke, ''J. Chem. Soc.'', ''Chem. Commun.'' 1990, 132.〕 Mixed chalcogen halides also exist. == Oxidation state +5 (PX5) == In the gas phase the phosphorus pentahalides have trigonal bipyramidal molecular geometry as explained by VSEPR theory. Phosphorus pentafluoride is a relatively inert gas, notable as a mild Lewis acid and a fluoride ion acceptor. It is a fluxional molecule in which the axial (ax) and equatorial (eq) fluorine atoms interchange positions by the Berry pseudorotation mechanism. Phosphorus pentachloride, phosphorus pentabromide, and phosphorus heptabromide are ionic in the solid and liquid states; PCl5 is formulated as PCl4+PCl6–, but in contrast, PBr5 is formulated as PBr4+ Br−, and PBr7 is formulated as PBr4+ Br3−. They are widely used as chlorinating and brominating agents in organic chemistry. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phosphorus halide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
