    en.wikipedia.org/wiki/Phosphorus_pentachloride

    This trigonal bipyramidal structure persists in nonpolar solvents, such as CS 2 and CCl 4. [5] 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]

  3. Phosphorus pentafluoride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_pentafluoride

    Phosphorus pentafluoride is a Lewis acid.This property is relevant to its ready hydrolysis. A well studied adduct is PF 5 with pyridine.With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula [PF 4 (NR 2)] 2.

  4. Molecular symmetry - Wikipedia

    en.wikipedia.org/wiki/Molecular_symmetry

    Molecular symmetry is a fundamental concept in chemistry, as it can be used to predict or explain many of a molecule's chemical properties, such as whether or not it has a dipole moment, as well as its allowed spectroscopic transitions. To do this it is necessary to use group theory.

  5. Phosphoryl chloride - Wikipedia

    en.wikipedia.org/wiki/Phosphoryl_chloride

    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.

  7. Dipolar compound - Wikipedia

    en.wikipedia.org/wiki/Dipolar_compound

    In organic chemistry, a dipolar compound or simply dipole is an electrically neutral molecule carrying a positive and a negative charge in at least one canonical description. In most dipolar compounds the charges are delocalized . [ 1 ]

  8. Acetyl chloride - Wikipedia

    en.wikipedia.org/wiki/Acetyl_chloride

    Acetyl chloride was first prepared in 1852 by French chemist Charles Gerhardt by treating potassium acetate with phosphoryl chloride. [4]Acetyl chloride is produced in the laboratory by the reaction of acetic acid with chlorodehydrating agents such as phosphorus trichloride (PCl 3), phosphorus pentachloride (PCl 5), sulfuryl chloride (SO 2 Cl 2), phosgene, or thionyl chloride (SOCl 2).

  9. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Note that the dipole moments drawn in this diagram represent the shift of the valence electrons as the origin of the charge, which is opposite the direction of the actual electric dipole moment. The bond dipole moment [5] uses the idea of electric dipole moment to measure the polarity of a chemical bond within a molecule. It occurs whenever ...
