In the solid state PCl 5 is an ionic compound called tetrachlorophosphonium hexachlorophosphate formulated PCl + 4 PCl − 6. [6] Structure of solid phosphorus pentachloride, illustrating its autoionization at higher concentrations. [7] In solutions of polar solvents, PCl 5 undergoes self-ionization. [8]
In chemistry, a hypervalent molecule (the phenomenon is sometimes colloquially known as expanded octet) is a molecule that contains one or more main group elements apparently bearing more than eight electrons in their valence shells.
In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid. [1] This is one geometry for which the bond angles surrounding the central atom are not identical (see also pentagonal bipyramid), because there is no geometrical arrangement with five terminal atoms in equivalent positions.
A pentachloride is a compound or ion that contains five chlorine atoms or ions. Common pentachlorides include: Antimony pentachloride, SbCl 5; Arsenic pentachloride, AsCl 5 ...
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. [4] It is mainly used to make ...
The Louvre, the world's most-visited museum and home to Leonardo da Vinci's Mona Lisa, has requested urgent help from the French government to restore and renovate its ageing exhibition halls and ...
From January 2008 to December 2012, if you bought shares in companies when Hector Garcia-Molina joined the board, and sold them when he left, you would have a 47.8 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
In chemistry, octahedral molecular geometry, also called square bipyramidal, [1] describes the shape of compounds with six atoms or groups of atoms or ligands symmetrically arranged around a central atom, defining the vertices of an octahedron. The octahedron has eight faces, hence the prefix octa.
