  2. Sulfur hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_hexafluoride

    6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. [citation needed] Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents.

  3. Octahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Octahedral_molecular_geometry

    When an anionic ligand replaces a coordinated water molecule the reaction is called an anation. The reverse reaction, water replacing an anionic ligand, is called aquation. For example, the [CoCl(NH 3) 5] 2+ slowly yields [Co(NH 3) 5 (H 2 O)] 3+ in water, especially in the presence of acid or base. Addition of concentrated HCl converts the aquo ...

  4. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.

  5. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  6. Hypervalent molecule - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_molecule

    An LCAO in, for example, sulfur hexafluoride, taking a basis set of the one sulfur 3s-orbital, the three sulfur 3p-orbitals, and six octahedral geometry symmetry-adapted linear combinations (SALCs) of fluorine orbitals, a total of ten molecular orbitals are obtained (four fully occupied bonding MOs of the lowest energy, two fully occupied ...

    No trifluoride is soluble in water, but several are soluble in other solvents. [57] The tetrafluorides show a mixture of ionic and covalent bonding. Zirconium, hafnium, plus many of the actinides form tetrafluorides with an ionic structure that puts the metal cation in an 8-coordinate square antiprism. [58] [59] Melting points are around 1000 ...

    en.wikipedia.org/wiki/Thiophosphoryl_chloride

    Thiophosphoryl chloride has tetrahedral molecular geometry and C 3v molecular symmetry, with the structure S=PCl 3.According to gas electron diffraction, the phosphorus–sulfur bond length is 189 pm and the phosphorus–chlorine bond length is 201 pm, while the Cl−P−Cl bond angle is 102°.

  9. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    Bent's rule is able to characterize molecule geometry with accuracy. [11] [5] Bent's rule provides a reliable and robust framework for predicting the bond angles of molecules. Bent's rule accuracy and precision in predicting the geometry of real-world molecules continues to demonstrate its credibility.
