  2. Phosphorus trichloride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_trichloride

    Phosphorus trichloride is commonly used to convert primary and secondary alcohols to the corresponding chlorides. [14] As discussed above, the reaction of alcohols with phosphorus trichloride is sensitive to conditions. The mechanism for the ROH →RCl conversion involves the reaction of HCl with phosphite esters: P(OR) 3 + HCl ⇌ HP(OR) + 3 ...

  3. Phosphorus halide - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_halide

    Phosphorus(II) halides may be prepared by passing an electric discharge through a mixture of the trihalide vapour and hydrogen gas. [ citation needed ] The relatively stable P 2 I 4 is known to have a trans , bent configuration similar to hydrazine and finds some uses in organic syntheses, the others are of purely academic interest at the ...

  5. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  6. Diphosphorus tetrachloride - Wikipedia

    en.wikipedia.org/wiki/Diphosphorus_tetrachloride

    Near room temperature, the compound degrades to give phosphorus trichloride and an ill-defined phosphorus monochloride: P 2 Cl 4 → PCl 3 + 1/n [PCl] n. The compound adds to cyclohexene to give trans-C 6 H 10-1,2-(PCl 2) 2. [1]

    Lanthanide trichloride, LnCl 3, a class of chemical compound composed of a lanthanide atom and three chloride atoms. Lawrencium trichloride , LrCl 3 , a compound synthesised in 1969 expected to follow other actinide trichlorides.

  8. Hypervalent molecule - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_molecule

    For example, in phosphorus pentafluoride (PF 5), 5 resonance structures can be generated each with four covalent bonds and one ionic bond with greater weight in the structures placing ionic character in the axial bonds, thus satisfying the octet rule and explaining both the observed trigonal bipyramidal molecular geometry and the fact that the ...

  9. Thiophosphoryl chloride - Wikipedia

    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°. [8]
